I didn't know that. wonder if a blood test can tell if ~I~ am high?

like, for instance, when first taking some anti-depressants or sleep aids, they can have side effects that could alter your driving ability, but after awhile, the side effects dissipate and driving is fine. what about someone who's been smoking daily for ~30 years? (or much less!)

I'm sure a person like that would have plenty in their blood... but 15 minutes after smoking a j, rest assured, the buzz is gone.
