Yeah man,im an all day toker,always drive when im stoned and never below 80,only time i have a prob is when ive been toking all day and ive got to drive long distance,i find i get tired easily.And ive never had an accident and only times ive ever came close is due to other twats on road.

Think it differs from person to person tho,one guy i knew would take two tokes and whitey for next half hour so he couldnt do shit...

Cheers
