As Adam Sandler wrote in the lyrics for the "Pot Head Anthem" (sung to the tune of "The Star-Spangled Banner"): "Oh say I can't see/Where the heck's my Visine?/And my eyesight's not keen/I hope you're not driving."

Unfortunately, the Centers for Disease Control and Prevention reports that during 2018, around 12 million U.S. residents 16 and older said they'd driven while under the influence of marijuana.

In June 2019, the American Automobile Association (AAA) reported that almost 15 million drivers admitted that during the previous 30 days, they had gotten behind the wheel of a car within an hour of using marijuana, doubling their risk for getting into an accident.

That might not sound like a lot compared with the astounding 100 million people who annually admit to driving under the influence of alcohol, but it's still a serious and growing problem as more places make the use of recreational marijuana legal.

People ages 21 to 25 are most likely to smoke and drive; those 16 to 20 are second most likely — and they're at greatest risk for accidents anyway because of their lack of experience.

Many folks don't realize that the impairing effects of marijuana can last for four hours or more, or that according to the AAA, today's pot is often 10 times more powerful than the weed used in the 1970s.

So, don't make an unforced error that'll cause you a lifetime of pain. No smoking (or munching) marijuana and driving. If it's legal where you are, enjoy. Just stay home.
