I have done a fair amount of research trying to find causality within the results of available studies (NIH.Gov) mostly. The reports of harmful effects are things like lost IQ points and other 'impossible to link' conditions to substantiate claims. I can not find any study that directly links naturally grown (not chinese gmo weed that is then produced and sold for legal or illegal recreational use.) to any physical or mental condition that does NOT contain words like, 'suggests' (a link between said condition or result, and clean natural cannibis. Words like 'may' 'could' 'seems' might', etc. This is fear porn from the Sacklers. I am talking about a plant. Grown and cultivated by a free Patriot, for their own use. Compare that to studies on Flouride, alcohol, or any of the common medications in use today. Look up the side effects of the top ten medications is use today. It is horrifying. Cannibis treats many of these conditions, and does it better, cheaper, and with far less damaging side effects.
