Pot also still stays in your system for a month or more after you've stopped smoking it.

Which means that any urine tests can detect it very easily. I know a few people who smoke it. And these are mainly bums who are living either in the streets or with or off others who smoke pot.

They either can't or won't find a job. Of course, I don't associate with those type of people. And anyone who is about to light up a "joint", as they call it, I get away from them. Even if you don't smoke pot, like 2nd-hand smoke from cigaretts, you'll STILL be affected by it.

Only with pot, if you stay in the room or house long enough where it is being smoked, you'll get a contact.
