Farmington police say 21-year-old town resident Robert Michelson called about 8 p.m. Thursday.
When a dispatcher told him he could get arrested for growing pot, police say Michelson said thank you and hung up.
Police officers went to Michelson's house and say they seized a small amount of marijuana and drug paraphernalia, while Michelson admitted he bought seeds and equipment for growing.
Michelson was released on $5,000 bail after being charged with marijuana possession and other crimes.
A woman who answered the phone at his home Friday said he wasn't available for comment, and it's not clear if he has a lawyer.
Transcript of the 911 call
Dispatcher: 911, what's your emergency?
Michelson: Uh, let's not get into that yet.
Dispatcher: If it's not an emergency you don't call 911 sir.
Michelson: Well, I have a legal question.
Dispatcher: Is it life threatening or an active crime in progress?
Michelson: Crime in progress possibly.
Dispatcher: What's going on?
Michelson: I was just growing some marijuana and I was just wondering what, how much trouble you can get in for one plant.
Dispatcher: You're growing marijuana and you want to know...depends on how big the plant is?
Michelson: It's only a seedling.
Dispatcher: Well, it's possession. You can get pinched for a roach in the car.
Michelson: All right, thanks for the info.
