The only good news is it is reversable... coming from a former pothead. I smoked it multiple times every day for about 2 years. It took a few years to really be thinking clearly again once I stopped. While the drug is victimless and the stoner is harmless, unless s/he gets behind the wheel, those who say one can use the drug with no negative side effects are purly in denial. I support legalizing it only because I have a libertarian side and I think it could be taxed and it wastes prison space, but I will personally never get into the stuff again as all it does is assist in wasting time and productivity.
I used to say that pot doesn’t kill brain cells, it just causes you to forget how to use them for a while. LOL!
