I am suspecting my son of using drugs. I saw on the show on tv "Cops", that some drugs are put in cigars and smoke. My son is not a kid but 25 yrs old but still a kid to me. I wondered what type of drug could this be. He takes tobacco out of the cigar. found it in a trash bag where he had done that and on the commode seat of his bathroom. I would like to know what I am talking about before I approach him on teh subject. Do they use pot or some other drug to do that? ty.
