Weed? only did it once?

Chill out it stays in your system 30 days mainly in fatty tissue.....BUT your body makes cannaboids naturally, so you will always have some whether or not if you ever smoked. It's been documented in use for over 5000 years. Don't you think that God would have found a way to tell us if it was bad. I for 1 do not approve of government sticking their nose and propaganda into my personally governed space.
