Now that I’ve rambled on long enough, on to BLACKDOG who points out that marijuana (specifically THC), which stays in your system for a hell of a lot longer than alcohol. We would have to set standards on what are acceptable levels of influence and not just impairment. FST’s are an adequate way of judging impairment but what about influence? For alcohol we all know the acceptable level of influence is below .08% BAC, however you can still be arrested for being below .08% if you are still impaired as determined by FST’s (23152 (a) CVC vs 23152 (b) CVC).
