Kevin Williamson chides Prop 19 opponents:

Prop 19 would not change the prohibitions on driving while impaired. This is fear-mongering of the worst sort: "Oh, help! The stoned hippies are running over our children." California  has real problems, and these busybodies are worried about, in their own words, passengers in cars who may be high. Not drivers -- passengers. The only dangers presented by a stoned passenger are associated with an unscheduled stop at Jack in the Box.

It's the sort of argument employed when the facts don't justify your position.
