If cannabis were legal then there would be a test for it - just like alcohol do you think?
All good don't ya think? Re: the test.
I have driven while prolly been over the limit (alcohol-wise) in a time of emergengy.
Long time ago my (then) GF's ex threw a pick axe at her car - hmmm
Had to save her...
Ahhh times change - not fun, don't do it.
