  1. I may or may not have experienced some cognitive dissonance while viewing this presentation.

  2. Use cannabis in its natural state. Its known that trying to separate and synthesize the components does not produce the health effects that the whole natural plant provides. Its cheap and all over the world. What greedy bastards are trying to do is selling anaturally growing worldwide cheap as dirt plant.

  3. The hardest task for a TED- speaker is to separate the real valuable facts and knowledge, fro the manipulated information and fake news… If you watch this one carefully, you will realize what I'm talking about…

  4. Armée d'0rient was rendered useless by the thc effects of hashish, 1798. Napoleon

  5. The word Assassin comes from Arabic root "Hashish" for cannabis Jihad 'fighters' dose themselves before going on their infidel killing spree. Singing apotheosis to it at TED somehow paints quite different picture.

  6. This talk is actually not about the effects of cannabis but about the isolated effects of THC. Her views here about the effects of THC on the endocannabinoid system may be very interesting to the pharmaceutical industry, but to those of us wanting to understand the effect of THC when You use the plant naturally it is almost irrelevant.

  7. Very disheartening for a respectable scientist to present hypothesis as fact and fear mongering in her talk.

    WHERE is the reference to THC inducing apoptosis in cancer cells, where is CBDs regulation of Dravet's syndrome?!!! Yet another scientist hiding behind political fear to disrupt the flow of the truth about Cannabis!

  8. I'm a excessively aggressive cannabis user I smoke everyday all day when I wake every 30 mins and before I go to bed I can go day's without smoking I don't stress out go through withdrawal it actually helped me quite opioids when it comes to negative effects just one to my wallet!

  9. Here's your data: in America, for instance, tens of millions of people have been consuming THC on a regular basis since the mid-1960's. This group is certainly large enough to draw scientific conclusions from. Such as, there isn't a single negative health effect that can be identified within this group that doesn't exist in the whole population. There's been no increase in schizophrenia as a percentage of population. Cancer, diabetes, stroke and heart disease are in no way elevated in this group. Conversely, we know for a fact that tobacco, fast food, soft drinks and Republicans actually kill people on a regular basis, all in their own way. With tobacco, our response has finally reached a proportional level. With fast food, soft drinks and Republicans, we are firmly in denial. The attack on marijuana began back during the Depression. A decade later, Congress held a hearing on marijuana, wherein a doctor from the AMA testified that he could see no harmful effect from using marijuana. Rather, it made people calmer. One of the Congressman replied "doctor, if you don't have anything to say to help us, why don't you just go home?" That's America. We make up our mind about something and the persecution begins. So, while this video was interesting, Dr. Ross' conclusion that more data is needed, simply ignores the overwhelming data that exists.

  10. She did a great explanation on the endocannabinoid system but when she talked about cannabis THC i felt like she wasn't as confident as before

  11. Cannabis has been around for years and used in this country for hundreds of years. This sounded more like a Pharmaceutical talk for drugs not the plant and its well founded medicinal benefits. Granted research is scant here in the US but we have been funding Israel for years and they have tons of research on cannabis benefits as well as Spain!

  12. As a medical student, I could only dream of having a professor explain medical conceps in such an understandable way

  13. Singing mimics cannabis to some biochemically tangible degree

    Think about Sachmo and his outspokenness for cannabis, slaves singing to cope

    Oh, yes, something to it all

  14. Interesting in that she postulates that Cannabis affects the endocannabinoid system by chance, saying it is a question of probability only.
    I'm not so sure.

  15. How sad to have so much excellent information about the ECS and so little understanding of cannabis and it’s compounds. Probability? Are we serious woman? More propaganda. Learn about terpenes already.

  16. She TOTALLY left out the Terpenes and Flavonoids that are important in the "entourage effect"….her lecture is woefully incomplete at best. Grade D

  17. She’s missing the point just like the government funded research has all this time. Researching single compound the plant does not come with just thc and we should not use just thc

  18. Felt like she was walking a fine line and did not want to be seen as endorsing cannabis. I get it but didn't really get much out of this talk.

  19. ECS Biochemical pathways that your body uses for Omega three fatty acid metabolism are the same pathways that cannabis' actives act on as well. the arachidonate signalling system / Arachidonic acid cascade. phoshpolipids in the cell membrane create endocannabinoids, essential fatty acids are used to keep cells @ optimum lipid capacity … ECS relies mostly on lipid metabolism of catalyzed enzymatic amides and intracellular ions

  20. 13:15 – THC is a non selective weak agonist with Low binding affinity… ECS still works fine with THC present

  21. Sea Squirt Developed the Endocannabinoid system a few billion years ago .
    it's predicted that cannabis has been forming phytocannabinoids for 50 million years … CBDA is the prime cannabinoid
