My tutor in school (for registration and shit) used to be a narcotics officer, and he is the coolest person ever, he said when he was a cop, that he was like undercover getting in with dealers, and had to like be shooting up and shit to look the part, so he must have a lot of will power to just stop doing that shit..
Also he said, if me or my mates get caught with weed, not to deny it or hide it, and the cop will let us go and not confiscate or anything because it's too much paperwork for them.
And he used to chill in the classroom with us at lunch with the door locked so we could roll spliffs in peace and not get caught, so he's a cool guy. On the last day of school, after the last exam he went for a smoke with us (just cigs) but that was cool of him, as he would have got in trouble if found out

Sorry if this was hard to read, i have an ice lolly in my hand as i'm typing, so it's hard......sorry... Josh
