I never smoked marijuana or had any form of it in my adult life and at age 55 , my Mother died of cancer in 2013 . Marijuana was the only herbal medicine that helped me through many difficult days. I used it at bedtime to help me relax and I worked full time as a nurse in the daytime with no side effects. I was calm at home and able to grieve without making me sick or crying constantly.

Using medical marijuana for 7 months now. Blood pressure 118/78. Best reading since my mastectomy in 2013. No heart meds. No anxiety meds. Works for me.

Is anyone else in this comment section blown away by this mans ability to not only present, but actually TEACH?

A friend of mine was the MOST OVER MEDICATED person I knew with opioid pain killers. He was prescribed about 3 times as much as the average chronic pain recipient. Using THC and CBD he was able to quit ALL OPIATES. Good for you Brett !!

Diagnosed with multiple sclerosis in 2005, started medical cannabis in 2010 and have been symptom free since. I grow my own all natural, organic, probiotic grown cannabis. I eat it, I vape it, I apply it topically. I get it into me anyway I can. It has also saved me from a sever opiate addiction. Cannabis saved my life.

I wish they would focus this much on talking about the effects from pharmaceuticals like pain meds, antidepressants, stimulants and so forth.

I’ve suffered from chronic depression and anxiety and migraines for more than 50 years. Around two months ago, I started taking CBD and lion’s mane mushroom supplements. I have never felt better. No depression, no migraines. I sleep like a baby. Amazing!

I stopped smoking cannabis over ten years ago. Wanting to be a positive role model in my children’s lives. I’m a disabled veteran and was dealing with the VA and their pharmaceutical medicines. Over a six month period I dropped a 65lbs and not by trying. Being rushed to the hospital three different times because I’d collapse due to lack of nutrition and being so badly dehydrated. Every test you could think of for a man in his 50’s. They found nothing. Actually my heart, blood pressure and bloodwork are immaculate. When I was not smoking cannabis I had high blood pressure. Found it extremely difficult to lose weight. I was always told my blood pressure was so bad I was looking at a stroke or heart attack. I think I’ll just stick to the natural plant. The past 30 years the medical field has really lost my respect

I am a medical cannabis exemptee. I smoked two joints of high THC (26%) and low CBD (0.3%) cannabis. I smoked them back to back prior to a treadmill heart exam. I had zero issues show up. They said I had "the heart of a teen-aged athlete". Cannabis is my only prescription and I am senior citizen. I am delighted with my health.

I'm 67 and have consuming pot off and on over 50 years. It's the only thing that relieves sciatica and I went from smoking to vaping to reduce lung impact. No heart problems or any side effects except a need to jam out to great music.

Every physician needs to be more knowledgeable about this topic. Excellent talk. Thanks.

A heart transplant doctor recommended I do edibles because over the counter pain relievers were effecting my kidneys. I did it and it helps to ease the pains I have. This is my go to for all my aches and pains and I will never stop using it. BTW my kidneys recovered and no heart transplant for me for now. God bless Marijuana and it's effects in alleviating my pains.

I’ve smoked pot since I was 15 years old when I was in my mid 30s I quit due to my kids and starting church after I quit in few years my blood pressure escalated my heart rate kept rising and I had 3 heart attacks in my mid 40s afterwards I was on tons of meds after a few years I started smoking pot again in months my blood pressure dropped to normal my heart rate became normal my out look on nerves became settled and I’m no longer on any meds not even aspirins That you God for this plant it’s saved my life I’m 58 now and feeling like 25 and healthy thank you lord

I’m 51 and smoking weed since I was 14. After my first hit, I felt incredible. Never had paranoia. When my mom caught me in my teens, I told her it’ll be legal someday. Here we are!

I like this guy. I could listen to him all day. It's always better to talk and understand benefits and risks. If only they had this back in the 60's. Same goes for hallucinogens.

A friend of mine with MS went from having to be in a wheelchair to not only not needing one but going out and dancing. All because of thc and CBD. It changed her life…so much so, she opened her own store which sells everything from creams, patches, etc.

I quit smoking weed a long, long, long time ago.......it's been probably 2 weeks.

I loved this presentation. Thank you Dr. Oh, for this thoughtful and concise, yet in depth lecture. It was most enjoyable to learn more Cannabis Science with you. After 35 years of cannabis self therapy, i'm now a legal medical patient here in the UK.

Watching this presentation I felt he was speaking directly to me. Taking antidepressants and smoking cannabis ended up in ER, defibrillated, and airlifted to Toronto General for ablation. A few months later started on a Beta blocker, and HR dropped to 35 bpm. After Holter recommended for another Ablation but after watching this I think I found the real problem. Stopped cannabis and Beta-blocker a week ago and HR is back to normal and the best I have felt in years. Thank you, Dr Oh from the bottom and the top of my heart.

Diagnosed with leukaemia in December 2019….started taking RSO Cannabis oil…fast forward to December 2021…I am clear of leukaemia 👍👍.

I live in Canada. I started taking CBD oil legally because I was diagnosed with severe arthritis and was waiting for knee surgery and hip surgery. In about 5 weeks the pain was gone, and I declined the surgeries. In addition my heel spurs stopped being an issue. My expensive cane is at my door as a reminder of where I was. The fact that this substance was made illegal for several decades is a travesty. Anyway I recommend it to all my medically challenged friends.

Very rational and well-explained presentation. Takeaway: Don't use weed if you're taking certain specific Rx drugs, take edibles or oil but be careful of dosage. If you have heart trouble, avoid weed.

I first tasted cannabis as a 19 yo Marine in '70 and have smoked ever since , never have cared for hangovers from beer and most of the violence and dangerous behavior has happened while around alcohol . This is a very interesting and helpful video .❤

I’ve been smoking weed since I was 17 and still do. I’m 76 and still hike, lift weights and am slim.

Man I love when people like that guy explain things with full passion

I'm Dutch. I worked in Coffeeshops, I smoked in Coffeeshops. I Started smoking all kinds of Cannabis and Hasisch at the Age of 14. Each Day, Day in Day out. I continued that habit till approx 45 Years old. At 50 years old I had a major Heart Attack! The doctors brought me back like 3 times in the helicopter... the tobacco along with weed caused major damage in my body. For children it has negative influence on brain developing. I dropped school because of that. Believe me. My best smoking buddy from the old days still smokes afer 45 years, he has a pacemaker implemented now. What do I want to say here? Just do not consume too much! Some day it will take you down.

With all due respect, Dr. Oh, you are a captivating speaker and presenter. Thanks for the wisdom here sir.

I first smoked pot at 18. I'm now 70, and still smoke, though not as much as I used to. Very little alcohol. I've never had a cardiac episode nor do I know anyone that has experienced one related to pot. I had a good career as an RN for 27 years. That's where I got all my hemostats from. I use a pulse oximeter occasionally when I smoke. I've never had a drop or increase in heart rate, and my O2 levels never change. I also grow my own, so I know it's not adulterated. Happy trails.

Stage three colon cancer survivor here. THC is my go to drug daily. It eases my pain. It helps me not use strong opiates also. Pot helps me relax,it helps me eat.It works very well for me.

If our government really cared about our health and well-being, things like cannabis research would not be illegal.

Cannabis became cardio toxic for me. Dr. said when symptoms started get to the hospital. If IV drugs didn't convert my heart rhythm I could be shocked. Took a couple close calls before I quit using cannabis. It will be my go to when my time's up.

Using cannabis for 40 years and have had no problems.

Pot and aerobic bicycling were the co-treatments I used to recover from 2 problems. One, I was addiction to street drugs. Two, I had an eating disorder. 43 years clean and eating well. Resting Heart Rate average is around 52. BP is great as well. All glory to God.

Please note that all the cautions you are listing for cannabis apply equally to all pharmceuticals as well. They work for some and not for others, they need to be individually titrated (and often are not), and they have interactions with other drugs or foods, and can have detrimental side effects .

I was a pothead for many years before it was legalized for medical use. I hadn't smoked for about 25 years. When anti inflammatory meds quit working, I got a medical card and found a dispensary. The employees spend a great deal of time answering your questions to assure you find the best product for your needs. I have tried CBD in the past with little result, but these are far superior products. I take gummies, but I also do the buds. Not all day or everyday. But it helps me deal with my hip and knee pain, and since I knew what Indica and Sativa, thanks to the staff, I was able to try several different strands in joint form, and see which I preferred. They always address my concerns and answer my questions.

After 24 yrs in U.S. Marine Corps, had 14 spinal surgeries, left knee & right ankle rebuilt. I’ve been using cannabis for pain management for over 5 years. I buy several strains based on their terpene profiles and what the different terpenes do for me. Then I mix the strains to come up with a blend that handles the symptoms I live with. I keep a journal of what blends of terpenes/ cannabis and quantities used in the blends that I need . i.e. Back spasms-Mercene Anti inflammation-Caryophyllene Etc…. Mixing strain’s works awesome, I use a coffee grinder to mix my blends Save the Keif it’s the original concentrate! Pain was my constant companion prior to cannabis! Orlando, Florida👍😎

They did a study in Canada that said the THC tunes down the carcinogens that causes cancer in the smoke. While it gives you the munchies it spends up the breakdowns of sugars in your stomach. This plant is truly a miracle and when you sit down and study you see how this plant can change the world.

Just a note: Our beautiful, big dog was 10 years old when we found his hips were faulty and he suffered much pain. My daughter had been given a gift of brownies from a young man who was allowed to grow his own 4 plants. She had a new baby and did not want to be inattentive or sleep too soundly. We gave the dog a tiny smidgeon of the brownie one night. He slept like the proverbial rock. EVERY night for the rest of his life, at 5 o’clock he sat under the brownie cupboard, begging us in his (talking)voice until he was given his smidgeon of brownie.

Chronic Pain Suffer since I was 19. Almost weened off my opiates using Cannabis. Didn't try Cannabis till I was 30, it has changed my life with pain and ADHD.

I lost my long-term partner 8 years ago, leaving my spirit and heart utterly broken. I started vaping weed and it has kept me alive, kept me from killing myself. Thank you, Mary Jane. My heart is still broken but I am still here. Update: it is now 8-27-23 and I am retired. I was having chest pain and high BP so I stopped drinking alcohol and caffeine, and stopped using weed three months ago. I am doing much better! The weed was great while I needed it but now I don't. We all do what we need to do to get through the dark times. Thanks for the nice messages. Bless y'all. Stay well.

I wish if this guy could explain about any kind of information, not only about Cannabis. The way he speaks/explains is outstanding. Thanks Dr. Oh.

I just watched the video because it popped up, and so glad I did, thank you for educating us .

Using it for about six months now. My anxiety and depression has decreased exponentially. Only use a couple of puffs before going to bed.

The healing of the planet. On so many levels. But as with everything: moderation and common sense are key. Informative and balance lecture. Kudos.

I am 54 and never smoked pot until I was waiting on my second spinal surgery. I've had cancer, 3 spinal surgeries, including spinal fusion. I live in dreadful pain. I started using delta8 gummies for pain. I'm not on a load of pain medicine. I know it sounds bad, but I am just trying to live w chronic pain

I can't afford some of these products, but, I use THC to sleep. I came out of a horrible childhood, I have stomach issues so don't drink alcohol, and then I had a vehicle accident and got quite a head injury, and I have Fibromyalgia, ME/CFS, plus other things like Hemachromatosis, Emphysema, etc so I consider THC a gift from God! For some reason I can tolerate a lot of pain, but, lack of sleep can turn me into a different not very nce person! Now, I sleep well and everyone loves me again! I am SO grateful for THC...so grateful. I'm 66 so don't really want to think too much about long term effects 😏

I’m so glad I found this video! I’ve been a cannabis user and tobacco smoker for many years. I tried and failed to give up the tobacco many, many times. I never wanted to give up the cannabis because, since menopause, I’ve relied on it to help with stress and serious sleep problems. Eventually, I found CBD capsules, which I take at night and I have now been smoke-free for 9 weeks BUT… I also take Amlodipine and Amitriptyline for BP and migraine. Your segment on CBD interaction with these medications has given me pause for thought! Thank you for the education 😊

This dude is phenomenal in presenting. He makes you listen without that you need to pay attention.

Outstanding presentation. I worry that, with the decline in the quality of our schools and lack of science teaching, people are not going to be persuaded by facts. The coverage of grapefruit's effect on medication build-up is gold. Every medical and pharm student should be required to view this presentation.

I'm 43. Born and living in Holland. Smoking weed since im 19. Playing football (soccer) since im 9. Exactly 34 years now! Still going like a machine at midfield on sunday's!! 😊

This doctor is FANTASTIC !!! I JUST LEARNED SO MUCH and loved his personality. ❤ I have been exposed to Mariwana smokers since the early 70's ( I was born in 1963 ) and my brothers had a booming business growing it in our mothers garden. Police came often to get their share. I have never had any leisure time to actually sit down to relax so never had the opportunity to explore its effects. In 2012, I did smoke a few hits and became SO PARANOID AND DEPRESSED ABOUT EVERYTHING and mind you I was building my dream home and making 15 grand per month. I was suicidal and scared and was having palpitations and terrible chest pains and felt like I was having a myocardial infarction. Now I understand WHY I almost died. I will just stick to ice cream to relax. 😊

I take a hit at night to deal with insomnia. It doesn't always put me to sleep but laying awake doesn't bother me as much.

After 38 yrs of opiates, my Doctors pushed me to get my MMJ card. WOW, WHAT AN IMPROVEMENT!!!

Smoked for about a year daily and can definitely say it started to hurt my heart

Its great that we can have experts that can have a real discussion on this stuff now.

I broke my back at 18, developed and diagnosed with Ankylosing Spondylitis, a painful arthritic condition. I was taking tramadol and arcoxia for 10 years. Tramadol is an opiate based painkiller. I lost weight (I was around 62kg!), was constantly ill, couldn't eat, skin was grey and cracking, I was in trouble. I started smoking cannabis, a joint a day, mid evening after work and my workout. Fast forward to where I am now, I run, climb, I train grappling 3-4 times a week, I am 92kg and I can launch a man across the room with no back pain..... EACH PERSON IS DIFFERENT

Had a surgery with a very long and painful recovery a few years ago. Doctors prescribed hydromorphone, and promptly scared me out of using it with a lecture about how it kills people. OTC painkillers did nothing for me. I tried a dose of hydromorphone. Nothing. I could try taking more, but after the scare talk, I ruled that out. In desperation I tried vaping cannabis, and it probably saved my life. It got me through the worst of the pain and associated misery, allowed me to sleep, and the only side effects were a fresh appreciation of music and humor, and an occasional craving for sour cream and bacon chips. Over two years later and still not fully recovered, but cannabis is still a daily part of my life, mostly right before bed. I sleep better than I ever have, and my heart and lungs ace every test my doctor puts me through.

Been smoking all my life. I do not need anyone telling me what it is or what it does. I know it is the most awesome plant our dear God provided fir us. Fear not. It is the quality of your journey not the length. Stay alert alert, educate yourself. Live and love within your means. My motto.

I know a runner who smokes cannabis daily. Went for his 40+ health check. Was told he had one of the healthiest circulatory systems they had seen for his age.

I'm 66 now and have smoked the gangi since I was 15 ,fit as a fiddle, still live in the woods by myself and still do rock climbing and hill walking.

The only issue I have is short term memory And I also have short term memory problems

I do not CARE what the physical effects of weed are at all. I'm 60 and have been medicating myself for 45 of those. I'm a highly educated retired environmental professional who had a stellar career, ALL due to marijuana. As an abused infant and child my will and spirit were completely broken by the age of 8, and by 11 I had a pistol to my little head. I remember exactly where I was in 1975 when I first tried it, and it was life-changing. I seldom use it for "fun", it has ALWAYS been, long before the first dispensary, medicine for me, serious, life-saving medicine. I accomplished things in my career that will never be done again. I've stood in the face of militant youth, abusive cops, and violent bikers looking to do harm, I've juggled multimillion dollar projects on 2 continents, raised a family, and tried to stay benevolent and connected, ALL because of marijuana. I'm alive and my kids are here because of weed, I WILL NEVER regret using it as Creator always intended. It is literally a life saver for me and millions of CPTSD and PTSD sufferers. Where the myriad of big pharma meds failed, especially after I was shot during Katrina rescue, weed again came to my rescue. It is my friend and my savior to this point and to hell with ANYone who derides it solely out of their own stupidity and ignorance.

Regardless of what anyone says it does effect everyone differently. I work with many young kids who smoke and act like brain dead zombies, and some can function well. Me personally as I’ve gotten older it does made my mind wonder and often take me to dark places, sometimes it takes me to great places.it’s all about controlling those negative thoughts. I’ve smoked for 40 years and I can promise it’s not healthy for you, it does help people cope with certain conditions but I know 100% it has lead to some heart rhythm/racing problems I’ve developed. As mentioned in the video I believe it affects the whole circulatory system in various ways, also effects the nervous system. I always twitch much more when I’ve smoked. So I’m ready to quit after 40 years, can’t smoke forever….

The CBD being a blocker/inhibitor in certain biochemical processes within the liver in regards to different drugs👏🏾👌🏾. The research is becoming prominent in the cannabis field of study. This was a great watch!

My Dad and his Dad died of a Heart attacks @ 60, never smoked weed or cigs. I have smoked weed and eaten edibles my entire life, and yet I'm still here @ 68. I know my days are numbered, I'm keeping my weed.

The biggest problem with cannabis is the stress from it beeing illegal.

Interesting that he doesn't talk about the study showing that over 65 pot smokers have a progressively smaller risk of heart attack than the non pot smokers. And for the over 80 crowd pot smokers have 1/4 the risk of a heart attack! That's amazing. I'm 71 so I better get going!

People do not feel paranoid on marijuana. What they feel is self-conscious. Paranoia is a feeling people are out to get you.

I've been struggling with cptsd, among other things, one day recently, I took an edible, and I was able to see "outside" of myself and the harm drinking was doing. Since then, the euphoric joy that begins with the first drink, is gone. I'm drinking 1\3 less than I have in decades, and I'm glad.

What I can tell people from years of cannabis use myself is that it 100% causes rapid heart rate a lot of times and just because of that effect it can spark a major panic attack and it’s also a unique stimulant that differs than Amphetamines or caffeine etc which increases that mental stimulation and sparks a huge flow of thoughts and ideas which can lead to paranoia alongside anxiety with or without mental hallucinations not so much if at all visual hallucinations. It causes you to feel that time slows way down and music sounds extremely intense and your mind starts to see things in a different “light” so to speak. I have personally done legitimate psychedelics in the past and none of which ever gave me a “Bad trip” except for cannabis which is the only one ever to give me extremely horrible trips that were very uncomfortable. But that’s just me personally as far as a “bad trip” goes. The positives are euphoria and great focus on whatever you like doing along with appetite stimulation and relaxation/sleep for insomniacs. Relieves stress and makes you more talkative and causes laughter releasing dopamine and helps depression as well. It really does boil down to terpenes on how it affects your body chemistry 100% which I have proven for myself indefinitely.

In 2021, I went to Colorado to visit some family but stayed at a hotel my first night in town. Instead of waiting until I met up with family and had them instruct me on proper cannabis use, I decided to go directly to a dispensery and try some in my hotel room. I vaped fresh flower in a handheld vaporizer. I had smoked Cannabis when I was 14 but of course was ignorant of anything about it. I took 2 or 3 small hits from a tiny, miniscule amount of green leaves in a dry herb vaporizer. Then, sat down to have some dinner in my room. 30min later it hit me like a ton of bricks and I almost blacked out, lol. I layed down on the bed and didn't get up until the morning. Later, I learned the cannabis I bought was 30%!!! The amount I inhaled would have been around 40-50mg of THC, and I had no tolerance at all. A normal dose for first time user should have been about 5-10mg. Needless to say it was a very unpleasant experience and I didnt use cannabis again for several weeks even though I had full availability to it in Colorado. It's really important to talk with someone or do online research to understand the proper dosages. I thought I was starting with a tiny amount and didnt realize how potent it was. Since then I've experimented a lot and found the strains and dosage levels that work best for me. I prefer straight Sativa using a Live Resin vape. The Sativa doesnt affect my short term memory as much and the Live Resin extraction process makes the end product taste terrific instead of some weird chemical taste. Edibles take too long to activate and the affects are harder to control since the level of highness can be hampered or helped by the food in your gut. With vaping you feel the effects within 20min and if they begin wearing off you can just do one more hit to keep the buzz going. You have full control of when you want to get off the train. With edibles you're on that rollercoaster until the very end whether you like it or not. And if the high isnt as intense as you wanted you cant eat anymore because you might accidentally take too much and only find out 2hrs later when it hits hard.

Thank you so much for clarity. I'm a lifelong smoker of cannabis, I'm 70. I had an "incident" recently after taking an edible. I was "uncomfortable" and remembered 8 years ago when I had an episode that could be ranked as a heart attack, but without a healthcare solution to make so much as a note (Obamacare was still in the future) I could not get the help I needed. Thank you for your caring lecture. It opened my eyes.

Dr. Oh is a great lecturer. He manages to talk about a lot of touchy subjects in a neutral way, so he comes across as reassuring rather than alarming. Great information on the cardiac side of things. He doesn't say this, but what I got from the lecture is that If you have any kind of heart disease, stay away from cannabis.

Excellent, very thoughtful video and very well explained.

I quit drinking last June 2022 after years of trying to quit. I had a difficult time trying to sleep when I quit so my doc recommended edibles than a sleep aid prescription. I love how I don't feel any remnants of any hangover after edibles. Glad this video talks about this.

Dr. Ho that was the most honest explanation of Cannabis knowledge I ever seen ! Thank you !

DR. Oh is an amazing presenter. Tell a story while introducing the chapters that you are going to cover. Excellent.

I have used daily for 40 plus years . I don't advocate this , but it worked for me. We are pretty good at it now.

He's a great teacher. Incredibly engaging and credible. I love the stats too. I'm riding the green bar, gambling on getting past 75, then look at the health benefits of cannabis after that ! Looks like a risk that might be worth taking. I started smoking pot in the late 70's. Around that time, I was working as a cave guide at Waiutomo in rural New Zealand, where life was pretty laid back. We were so lax about our use of it, that I didn't think twice about flying, and even doing my 'first solo' about as stoned as I've ever been.. It wasn't planned. I just happened to get picked up on a road soon after a session, and ended up at the aristrip with a free flight going. It didn't even occur to me that being stoned was an issue. After all, the instructor was downing whiskey as he waited for me to land 🤣

How many millions of people smoke Cannabis responsibly and do not get heart issues? How many millions of people have smoked Cannabis responsibly since time began and did not get heart problems ? How many people in this study were unfit, had a poor diet and were Vit D, Magnesium, Potassium and Zinc deficient?

I smoked weed for 20 years. Stopped cold turkey 3 months ago. It was ruining my life, physically, professionally and mentally. My lungs, and heart, are thanking me.

I take, synthroid,metformin, lisinipril, Apixaban,cardezem, singulair, Lipitor, albuterol, potassium,magnesium, and calcium. 4 yrs ago I stopped Tramadol (20yrs) and Ambien(15yrs) and use med cannabis, Afib has calmed down intermittent episodes, sleep well, chronic pain has went from moderate/severe to mild. My daily life has improved! Went from 23 hrs a day on my back to being able to drive again and limited walking with rollator. I could not set up in a chair for more than 5-10 minutes, now no problems for 5-6 hours. Occasionally take a Tylenol but that’s it. Retirement is improving!😃

Ever since I've been taking CBD oil everyday since last week. I've chilled way out. Anxiety is almost 90% gone.

This is by far the best presentation I have seen on cannabis from a medical professional. I especially appreciated the information on THC & CBD interactions with other medications. THC tincture is just one option in my pain management toolkit and knowing how it interacts with the medications I have to take is critical. Thank you Dr. Oh for a non-judgmental, enjoyable and very informative talk.

Thank you for the info. More info than I was ever given before.

Excellent presentation. Making health personel aware of our necesity to educate on marihuana 101... The 'today' practice makes it an obligation. Thanks for the lecture.

So happy doctors are finally getting educated in the field of Cannabis. I want to encourage all Healthcare professionals to be careful casting judgment on people who choose to use this as part of their lifestyle or healthcare options. The pros vs the cons must be weighed, which I did not see presented in this excellent article.

I am so glad I gave up all weed and booze through AA meetings and living that lifestyle! I used for 30 years and couldn't stop and stay stopped at all until I changed my old ideas and took on a different set of rules to live by!! Thanks

After awhile I felt extreme heaviness in my heart ♥ After smoking weed similar to heartache,which is why I stopped.

Excellent and informative video. I'd love to see it's reach exceed 2.5M views because the specific medications he mentioned that have adverse or build-up effect in the body when mixed with CBDs are extremely common. We're all familiar with the warnings about eating/drinking too much grapefruit but many doctors don't even know to warn against the mixing of CBDs and certain prescription medications. It's also invaluable to know that marijuana has been "Frankensteined" into a substance dangerously more potent.

If you need a sleep aid...my wife and I found this lecture helpful.

I knew about grapefruit, but did not know about CBD. Thank you for the information.

15 minutes and 30 seconds of watching this guy and i already like him 👍

I met Dr.Oh when I had my cardiac rehab a few years ago. He’s done a marvelous job educating people. Thanks so much.

I quit weed a few days ago over cardiovascular concerns. This has solidified my position.

This leaves me with 2 questions: First, on the chart with the risk of heart complications from smoking, after around age 65 the risk of THC causing heart problems goes down and naturally as you age the risk goes up. It implies that THC is not a high risk factor for older people, which seems counter intuitive. In my thinking it has to contribute to the all cause mortality of aging. Second, I didn't hear him talk about vaping. Probably no data on it yet. I am told by the dispensary that there is just THC and a carrier oil in the vape and nothing else which would seem less harmful on the cardiovascular system. While I don't believe that inhaling heated oil has any benefit to the body, it would be nice to know how bad (or not) it is.

I'm off opiates for a destroyed back thanks to marijuana. I know it has side effects. And I'm grateful that life destroying addiction and overdose death is not part of it. Thanks to MJ I live a much improved life with much less pain.

Excellent, *honest* presentation. I've been smoking cannabis for ~43 years, and learned quite a lot from this. The key is the honesty because we have always been fed the dishonest government-provided information which we know, through personal experiences, is suspect at best!

What a great teacher! Great information. Thank you so much for sharing this informative and interesting to watch.

Excellently exposed. Compliments. I LEARNT for the youngsters I observe, thus much obliged to this post and speaker. Regards
