That's absolutely not entrapment, my friend. The courts have traditionally defined entrapment as someone threatening you in order to make you do something illegal.

A cop soliciting a sale is not entrapment. A cop soliciting a sale and lying to you by saying he's not a cop is not entrapment. Even if he were to smoke weed with you while making or soliciting a sale, it's still not entrapment. The only way it's entrapment is if a police officer, or anyone, coerces you to do something illegal with the threat of harm to you or your family. Otherwise, it's all legal.

Be careful with whom you deal with.
