Driving high might feel safe. So why not? Driving high is dangerous, and so is riding with a high driver. It doesn’t matter if you’re over 21, and it doesn’t matter if you’re a “little” high or a lot. Using cannabis can nearly double the risk of a crash. Cannabis greatly affects people’s ability to drive safely and its use should never be allowed inside a vehicle.
Cannabis impairs many brain functions essential to driving. This includes task management, attention, processing, and vision. One study found that most drivers under the influence showed slow reaction speeds and riskier driving. It isn’t until three or four hours after smoking that you fully return to sobriety and driving becomes safe.
Despite the dangers of driving high, 55% of users have driven high at least once, 25% have driven high and drunk, and 15% have smoked while driving. This means that legalizing cannabis results in more high driving. States that have legalized cannabis tend to have more fatal car crashes than those that haven’t. Driving high is a dangerous combination that should always be avoided.
Cannabis use is harmful in itself, especially if you’re underage. The risk of damage only increases when driving high. If someone you know intends to drive high, it is important to take their keys if possible and never get in the car with them. One decision to ride with an impaired driver has the potential for deadly consequences and is never worth the risk.
