WHY THE EXISTENCE OF ONE SET OF MORONS ON THE ROAD JUSTIFIES THE EXISTENCE OF ANOTHER SET by gribbler If driving with a cell phone is more dangerous than driving while stoned, and cell phones shouldn't be illegal, then road safety alone is not enough to justify making marijuana illegal. Road safety is a stronger argument for banning cell phones than it is for banning marijuana. In order for banning marijuana but not cell phones to make any sense, additional justification is needed.
