Methamphetamine? I doubt it, meth wasnt discovered until the 70's-80's i have heard that the japanese took drugs for some reason or another, if it was in japan it was probably some sort of opiate. I have an extensive knowledge of drugs, we have discussed drugs and nothing but drugs in health class in school for the past 3 years. I feel like a walking encyclopedia for drugs. I have never and will never do them though, my dad would literally kill me, he said he would kill me and quite frankly he would, i would die if he found out i was doing drugs, i mean DIE literally, my dad can be a scary guy.
