The groups that do these studies need to keep doing studies, without regard to how useless they are, or else they don't get funding. Or, there's always some private organisation willing to fund them if their study concludes with something agreeable with said organisation's policies. Mainly because of how people suck so fervently at the study teat and treat as beyond the scope of criticism/scepticism.
It's because your brain is still developing. Have you noticed it says "heavy" pot smokers. That's like saying your destroying your brain when you "heavily" drink. No crap. A heavy amount of anything isn't good.
What's next are we going to spend millions to do a study to prove water is wet. Makes me wonder why we still pay taxes.
