ok i agree with dick here....sumone laced ur weed....opiates arent just herione....codiene, morphiene, oxy's, and lots of other drugs r all opiates. if u did vomit from smoking that one day then it must have been laced with an opiate....i really hope u dont lose ur son and i hope u get back at the fuckin asshole who laced ur shit....

good luck

later
