i think alot of it has to do the way ppl are taught abt drugs... all u ever hear are drugs are bad and so on and so forth... they nvr say "well pot isnt as bad as meth" or somthing like that... so wen u do pot u relize that its not as bad as everyone said it was so u automatically assume that meth and heroin are the same way... just because they dont teach you that some drugs are alot worse than others....
