Oh, indeed it is. I've driven high with and without bud on me many a times. As long as your car doesn't reek of it, there's nothing to worry about. If you're really paranoid, you might as well get yourself some eye drops for the ride. You know, just in case.

Driving high is so chill on country roads with no cars. Oh man, especially in the summer. It's beautiful. Now...busy highways are kinda annoying. You really gotta know what you're doing--ie. concentrate to a certain degree.
