I always assume that cops are out to bust sellers. I do not know if it is worth the paperwork and cost to try to bust someone buying. It would be interest to know difference in charges.. I know every state is different. The guy was Probably just short on cash and trying to make a buck . Going to Charge you enough to get his next bag. I think the biggest risk would be get losing a couple of bucks. I would just get the smallest amount possiable and build up some trust. Every transaction I have been in has started with lighting up.. Now I have had people ask me if I am a cop which I think is a urban legend that they have to tell you. They can lie thier ass off.

Sounds like I have more questions than answer......
