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.
The findings of that study were considered nearly statistically insignificant so every finding is qualified with “can” or “might” or “might contribute to” or “correlates”. Another junk study based on statistical semantics. Debunked here in the same med journal: http://m.pnas.org/content/110/11/4251.abstract
While people debate knife-edge statistics, you can go to any hospital right now and find many people with directly observable brain and body damage from legal alcohol, tobacco and pills. People whose organs are failing but they can’t quit. People who would die from withdrawal shock IF they quit. You will NEVER see such horror from pot use. There is no “maybe” or “might cause” with these legal drugs yet we allow them to addicts on demand for easily faked diseases and taxpayers pay for them.
There is absolutely NO reason besides profit for this twisted logic. Pot prohibition is NOT to keep us healthy “for the children”. It is a scam to take our rights and sell more profitable toxic addictive drugs.
