I got busted for selling heroin to an undercover officer at NA meeting

No, NA will continue to remain anonymous, it's you who has given up your anonymity by selling heroin.

That's a creative defense, but it surely won't prevail. I always suspected that NA meetings were a great place to score dope. You gave up your anonymity when you committed a felony. Hire a lawyer.

Not on that basis. Nothing done or said in a NA meeting is privileged and confidential with respect to criminal prosecutions, particularly a criminal act such as selling narcotics.

The fact that it was at an NA meeting won't be a defense, sorry.

No. If that was a defense it would create immunity not contemplated by the law. I suggest that you hire a good criminal defense lawyer. You face a serious charge and the DA won't react well to drug sales at a therapeutic setting.

Not going to work. There may be some merit to the idea that if you discussed selling narcotics at an NA meeting, that it may not be used against you but committing an actual sale to a UC is certainly not protected. If it was, every drug dealer in the State would open up shop at their local NA meeting.

Like everyone else has said, the NA issue doesn't sound like an actual legal defense. However, depending on the circumstances of how the transaction exactly came about, you MAY (and this is probably a long shot) have arguments for suppression of evidence. Appealing to the DA about how wrong it is for undercover cops to troll NA meetings to make arrests may help you get a better deal if the DA doesn't t want to encourage such police action. These are all big ifs, but if you want to fight the case get yourself a good lawyer to help you out, pronto.
