Do you think you are the best judge of whether you are safe to drive after smoking marijuana?

Brian P.Dunleavy reports,

Smoking marijuana impacts adults' ability to drive safely, yet most who use the drug believe otherwise, a study published Wednesday by JAMA Psychiatry found.

Adults in the study performed "significantly" less well on tests designed to assess their driving abilities, including reaction times 30 minutes and 90 minutes after smoking marijuana, the data showed.

They also had "borderline" declines in driving performance 3 1/2 hours after using the drug. By 4 1/2 hours after use, driving performance returned to normal levels, the researchers said.

However, nearly 70% of marijuana smokers expressed willingness to drive within 90 minutes of smoking marijuana, and had confidence in their ability to do so safely, according to the study.
