    Medical Cannabis and a Good Diet are a medical necessity for all those of us who have been innocently and ignorantly consuming such hard to avoid Mitochondrial Poisonous Polyunsaturated Vegetable Oils in our diets and got one or more of many more modern thus Metabolically Caused Diseases and CANCERS. These barely existed before about 1900 when industrially manufactured Vegetable Seed Oils and foods started becoming available. You need to exclude all manufactured snacks, takeaways, restaurant fried and manufactured foods to avoid all these vegetable oils. The ideal solution for ultimate healthy longevity is to go fully VEGAN and take Cannabis Supplementation to boost your damaged Endocannabinoid System until you are better (maybe 2 years or so) while getting all vegetable seed extract, typical industrially refined cooking oils out of your diet. You can certainly use some polysaturated animal food-based oil/fat as in all animal products if you are not quite so ill or worried about living as long and remaining perfectly healthy. Best luck from your optimally self reeducated and friendly family GP Dr David who wants to see you be actually cured of all the modern diseases that are definitely so dietary-based in origin.

    Most studies tell lies about Marijuana I know because I used to smoke it everyday, it may affect some people differently but it will never be as bad as pharmaceutical drugs it should be up to individuals what they would rather have and not up to politicians who want to keep money in big drug manufacturing companies because that’s what is causing all this dementia.

  6. Stephen Samuels on May 15, 2022 at 7:07 pm

    Realise that big pharmaceutical company’s control the research spending 90% of their budgets on any adverse effects of cannabis

  7. Zachary Sturgeon on May 15, 2022 at 7:08 pm

    Great video. You kept mispronouncing cannabinoids, though.

    I use it to control my thyroid, graves and my heart. It relieves stress and anxiety but it’s still illegal and medically it’s not even recognized as treatment when my doctors have all agreed the only reason why I’m still alive today is because I used illegally and still do. This is not a mistake or an oversight, our lives simply do not matter to corrupted politicians who understand the benefits marijuana offers. It’s just Pathetic…

  24. wpf312 on May 15, 2022 at 7:27 pm

    Frequent heavy users? Let’s leave my weight out of this ok?

  25. John M Lombardo on May 15, 2022 at 7:29 pm

    American propaganda is the reason the study’s of the cannabis plant has been oppressed, the laws on the cannabis plant were made to lock brown people and Asians in their prisons to take peoples liberties away. Not one person has died from cannabis use in the pass 3000 years of recorded history.The plant has always been a medicine and food since god made it, the Chinese people called the plant ma and it does work for ms, seizures ,anger, eating disorders, some form of cancers, chronic pain the list can go on of the medicinal uses of the cannabis oil derived from this wonderful plant god made. Aloha!!!

    C- needs to do more research but shows promise👁👁 try starting from the beginning 🤨🤨 does breast milk contain cannabinoids ? Grow your knowledge from this point, I will give you 1 more before 1937 flour was made with hempseed 👁👁🧐🧐 does it not say “give us this day our daily bread “ in the bible under the Lord’s Prayer. Now you have a little more knowledge, dig deeper and spread your knowledge. Reveal the truth and thank God🙏🏼🙏🏻🙏🏾🙏

    I know that I ones doubted herbal medicine even Dr Madida, so is everyone I believe  but right now I don’t longer doubt it again especially the herbal medicine from Dr Madida on YouTube which cured my idiopathic pulmonary fibrosis.

  29. Stephen Samuels on May 15, 2022 at 7:32 pm

    I think it still is a class a drug in the US which means it has no medical value,which stops it from being researched

  30. tom smith on May 15, 2022 at 7:32 pm

    I’m doing some med weed right now. Plus some beers…I’m 63….but now feeling 23. No kidding….

    1:40 Epilepsy can in some cases completely be cured by medical cannabis this is directly evident in the patients going from 50 seizures a day to literally 0 no case studies needed. Just be carful what you say because that is a belligerently obvious reality for this treatment and condition.
