No, on the opposite, weed and especially hashish was always great for me. The problem is that with these two it is impossible to tell how long you need to wait before your bloodstream is clean. I don’t want to lose my CC license because of that (for example, if I get involved in a car accident as a pedestrian and have subsequently blood tested).
It is zero level tolerance here for both drivers as well as CCers.
So smoking ganja would mean leaving gun for a few days at home. I prefer to be armed.
