show me ONE before-after study showing permanent damage to intellect or IQ in ANY adult that has used pot for any period. There are countless people who have used pot for decades and they can’t prove any before-after drop in IQ. People have been using it heavily for at least 50 years in the USA and we have no proof.
Alcohol abuse causes real permanent brain damage yet is sold in unlimited amounts.
Google’s pretty easy isn’t it. That’s just the starter, as more studies will show the common sense notion that it damages the brain whenever used, for good.
