No. I don't know a lot of people that don't wear seatbelts, but they all smoke weed. All of my friends that died in car wrecks weren't wearing seat belts and would have definitely tested positive for THC.

I don't know any old people that don't wear seatbelts.

The people I do know that don't wear seatbelts also live pretty otherwise high risk lives, drug dealers, strippers, street gang members,etc.
