honestly man, im not to sure, but coke and crack= coke and crack, amphetamines are speed, meth amphetamines are like crystal meth, thc is as everyone knows cannabis and opiates are heroin, oxycodone, hydrocodone and etc, so i dont see why it would show up. and i dont think since you havent done them recently that it wouldnt show up anyway, i think the only they can test for that is through your hair.
