drugs added to it? I know many drug dealers often use drug-contained cigarettes to get people addicted to it in the first place. But I am wondering as a person who has lots of smoking experience but who has never taken drugs before smokes a cigarette with drugs(heroin or meth) in it, can he/she sense the different taste/smell of this cigarette? I know in most cases they can tell if a cigarette is counterfeit or with inferior quality, but I don't know whether they can detect a drug-contained cigarette they are smoking. Thanks.
