Marijuana is a fairly short-term drug. It is only going to decrease your ability to drive for about three hours, which may not even be as long as a night of drinking alcohol would. Typically, experts agree that the effects wear off in an hour or two. In some specific cases, minor effects can linger for a day, but it's not as if you are experiencing the full impact of the drug for 24 hours.

The driver was reportedly driving at a high rate of speed prior to the crash. She was taken to a medical center where she was treated for minor injuries and released.
