We don't smoke and drive. Way too dangerous. Now, hold on, I don't think being high while driving is dangerous (for a habituated user). I think the exposure smoke gives you is dangerous to your freedom. Cops... We got pulled over last week and had just been vaping in our closed up truck. Not 2 minutes before being pulled over. Oh hell ! And this was a State Trooper, no local yokel. I was the passenger and riding without a belt (post surgery) and he saw the opening to pull us over. If we had just burned one we would have been busted. No doubt, we would have reaked. I tossed my rosewood unit (http://purple-days.com/Rosewood.html) to the floor where it blended in nicely, and rolled down the window. He came up on my side... After threatening us with $550 in tickets (he saw the scars and bruising and didn't care, unless I was carrying written exemption) he finally let us go with a warning. I sincerely thanked him and offered my hand, but he was an ass and refused to take it. If this little trooper only knew, LOL, Anyway, I have always wondered what vapor odor would be like to a non-weed user. The uninformed (and uniformed). But you just can't ask a nazi in jack boots... So is vapor stealthy? You draw your own conclusions. Do we smoke and drive? NEVER. Keep your eyes on the road, your hands upon the wheel. (And your vape between your legs.)
