Sadly, many people drive while under the influence of marijuana. Some even believe it makes driving easier and calms them while they are behind the wheel. In truth, though, driving while intoxicated from marijuana makes one twice as likely to become involved in a fatal crash, and the drug itself causes a number of side effects that can impair driving. As such, making excuses like those above is a sign that you may have a marijuana use disorder.

You can also determine if you have a marijuana use disorder by considering whether or not you can give up the drug while you are driving. If you have tried and failed to do so, this is a sign you need help. In addition, if you refuse to do so even after seeing all the evidence of the dangers of this behavior, you are likely struggling with a substance disorder. Marijuana can cause dependence and addiction just like many other drugs and alcohol, and those who use it every day in large amounts are especially at risk of developing a disorder.

Other signs that you may have a marijuana use disorder are financial issues caused by your use of the drug, tolerance to the drug’s effects, withdrawal symptoms when you are unable to use the drug, and prioritizing the drug about everything else. If you have experienced any of these or other serious issues—or if you are dealing with a severe consequence of driving while high—it may be time to seek help.
