I dunno about weed, but from what I understand the police there will nab you for drugs. They just rehabilitate drug users instead of just tossing them in jail. I have a tweaker cousin who has been in and out of prison his entire adult life. He may go clean for a while after getting out, but then he gets caught up with the same friends, then it's grand theft auto or something again and he's back in the slammer. If he had been rehabilitated, he may be drug free and wouldn't have a prison record and therefore he might get a job as a car salesman or something because he's a phony schmooze.
