Drugs, including marijuana, affect the way you drive—putting you, your passengers, and other drivers on the road at risk. Drugs can alter your perception, attention, balance, coordination, reaction time, and the other skills you need to stay alert and safe.

The effects from smoking marijuana only takes minutes. Edibles, however, take between 1-3 hours because food is absorbed into the bloodstream through the liver. Because it takes longer, the user may end up consuming longer amounts of the drug while thinking the drug isn't working.
