Alright I'm going to add a couple of driving while smoking tips here...

1) Put all of your stuff into a soda/drink stash can and put it in your cup holder. It may not have a ton of room but you shouldn't be driving with much anyway. I have an Arizona Iced Tea one and it rocks. I think most cops wouldn't even suspect anything as long as you played it cool. You can pick these up in most head shops.

2) When smoking out your car leave the windows cracked, not wide open but cracked. Smoke won't build up in the car and be visible to others, and it will still air out without letting others know what your up to.

3) Wear seat-belts it will give a cop one less reason for pulling you over and keep you safe.

4) The safest/most stealth piece to smoke with is a cig hitter. Looks like a normal cig to other drivers. Of course you can just duck down a bit when smoking bowls etc.

5) Don't speed I mean you can do a bit over but nothing to much or the police might pull you over.

6) Only carry what you need. If for some reason you do get caught, hey it happens, you won't get as serious as a charge. Only bring what you really need.

oh and..
