IMO it's really impossible to know for sure exactly what pot does, if it is damaging in the long term, etc. First of all because any website run by potheads is probably a load of shit. All they want to do is make pot legal so they can spend more time smoking it. Then there's the other end of the spectrum, the people who always tell you drugs are bad no matter what, and dish out a bunch of facts, some of which may or may not be true. It's quite pointless to debate this online for that reason.
