No, but if you haven't used marijuana before it's hard to understand how in pretty much every way imaginable it is safer than something like alcohol (the REAL gateway drug.)
@Dexter Bullcrap, as I have posted before about my one and only time trying pot, it scared the crap out of me. It wasn't laced with something (same pot my cousin used and gave me). I never tried another drug thankfully.
Pot reacts with different people in different ways. Like some meds list adverse reactions, well, funny you can't find a pot smoker that will admit it does not react the same with all people. Dope head have the same stupid comment, that it is harmless.
I remember it making me very excitable, the music seemed to get louder and louder, taste went way out of proportion, time slowed down to almost seemingly nonexistant. I started running until I passed out. I woke up and went back inside (trailer college) and slept for almost 24 hours. Again this was not some laced up version of pot, it was the same thing my cousin smoked. It wasn't even half a joint for goodness sakes.
Pot is unpredictable in the way it reacts to people. This 6'4" big ugly fellow knows if it can react to someone as big as me, it can do even more damage to someone of smaller dimensions.
