I drive high all the time. but I do have a few rules.

I only drive high at night when there is next to no traffic. I feel safer that way. I never drive high in heavy traffic, and if I do drive during the day, I avoid traffic as much as possible. No matter what people may say, it really is a lot more difficult to drive through rush hour high than sober. Your ability to judge the distance of oncoming cars is reduced greatly. I sometimes find myself waiting to make a turn for a car 1/8 mile down the road. That is, when I'm REALLY baked.
