I've dabbed in the car once while driving, but I was stuck in slow moving single lane traffic. I pulled out my rig nail errl and torch from my bag in the back, filled the rig, and then took two dabs before I got out of traffic. It made me feel better about the traffic and then that ride felt like it went real quick the rest of the way. No way I'd do it again. Way too much going on. Maybe if I was stuck in the eact situation again. Driving high dosn't effect my ability to drive at all, I take a dab before going anywhere. It just makes me obey the laws of the road a little more. I'm paranoid driving high or with a rig right next to me, so i drive safely and slow down to just below the speed limit at every hiding spot the cops have I know about.
And to help un-derail a bit, when it comes to dabbing in the car I love my double showerhead from kathy, it fits right in cupholders perfect. And it's smooth as butter so no coughing fits.
