if you would have read my posts you would have seen i am a legal smoker. i'm gonna test positive regardless. the law says "within 4 hours". there is NO legal, limit for pot. they judge it based on your actions. i'd beat it in court. they'd have to see me actually smoking to get it to stick. then it's my lawyer against them.
i don't fall on my face when i smoke too much either. i do black out when i drink though. that's a hell of a way to drive, isn't it?
just like you, i know my limits. i don't understand why you must continue to insult me when i clearly agree with you. nice way to carry on a discussion.
