I'll tel you what dude, give the mshit that won't kill them, but is laced with like heroine, and some other nasty addicitve, and really illegal shit, and alo, if you can, try to plant kiddie porn on them. THEN call the cops. If they already stolen, and smoked your super laced shit, then they will major fail any drug test that the cops give them. Plus with the kiidie porn then they are labled sex offenders, and that really fucks you up, like Kobe Bryant.
