It's guys like you that make pot smokers look smart. :lol:
Are you serious dude?
You don't think he can tell the difference between someone burning a joint or fresh weed growing?
Maybe it's the security guard smoking it in the stairwell, the OP doesn't even know if it's a tenant or not.
If you want to get technical, maybe somebody is smoking weed near the intake vents of the building, ever consider that?
Wasted (lol, sorry, have to laugh at your username again) just put an anonymous note on the wall across from the elevator on your floor, > "attention pot smokers, please try to keep your smoke contained so it doesn't stink up the hallways, thanks dude!"
End of story.
Meanwhile, some kid just died from taking prescription drugs or alcohol somewhere.
To all the haters, give your damn head a shake and open your simple, narrow minds.
