first, I'd like to say that way to many motherfuckers smoke butts out of ashtrays and off the ground. What makes that practice okay in people's heads? Anyway, a cigarette pack with two cigarettes in it is now the sign for laced cigarettes. When you find a pack of smokes with two left, they are laced, starting now. Now they must remain intact, so to the lacers, you must spray or liquefy your chemical that you plan on using in your "special" cigarettes. Now, we will have to vote on which brands to use, but I suggest Marlboro Reds in a box is for X adulterant and Newport in a box are for Y adulterant.
I will stop here. I just realized this is way too easy!
Kids, don't smoke butts.
* this is a real bad joke. Don't smoke cigarettes you find.
