Drug charges?

I had a complaint at my apt.about noise. The cops smelled pot came w/o a warrant, and searched inside. They..found about 10 grams of high quality pot and two paraphenelia items. They seized everything of course. Luckily, I havent been charged yet. But the officer said I have to call him in the next 5 days and give him any leads to possible growers. I dont know any! I dont even know the sellers. If I cannot provide him w/ insight into where the growing is taking place, I will be probably faced with some misdemeanor charges. What would they be? i know i'll go to court with some fines. Will they take my driver's license away? There is NO WAY that I am going to snitch and get my *** blasted by someone crazy. So I want to man up to the charges so no one else gets in trouble... PLEASE...Someone give me some advice on how to explain myself to the officer when I have to call him in 4 days, & anyone with any expertise in this sitaution, please reassure me everthing will be OK..

It depends which state you're in and how serious they take pot possession. In Washington its just a $250 to $400 fine for less than 40 grams of pot and the same for paraphenalia.
If you know some asshole thats a real jerk turn his name over to the cops. Me I would just say I picked the weed up from some crackhead in a park or on the street.

Generally possession charges don't lead to license issues. Not knowing what state you're in so can't be sure. I'd call the cop and explain that you would like to help but can't. If you had to defend that case you's stand a decent chance anyways which might explain why you have not been charged already.
