A good lawyer COULD get you out of it. You'd have to prove you were a long-time practicing Rastafarian or something. But I'm assuming you've already been busted, so that's basically impossible to do.

In Aus this wife and husband said they were Christians and used their plants to make the anointing oil. In the Bible where the ingredients of the annointing oil are listed (no idea where, not religious) it says Kaneh-Bosom. This was originally translated to Calamus. But the correct translation, translated into Greek is kannabus or something like that and then English is Cannabis.

You'd need a GOOD lawyer though.
