How long does it take after a person smokes marijuana before they can drive safely again? My husband goes over to our neighbor’s house all the time to smoke with his friends and then like an hour later he will be back and ready to drive me and the kids somewhere. He looks OK and he says that after an hour after smoking he is OK to drive. He drives fine and I cannot see any difference but it is still something that worries me. How long should he wait after smoking before he is OK to drive?

Stephanie Adams Says...

While I appreciate your faith in me, as a mental health expert and not a medical expert, I cannot give you an authoritative answer on this question. I did some research to see if there was anything out there that a medical expert had published to give you an answer, but everything I saw told me it depends on the person's individual reaction to the drug and the amount of THC in the marijuana taken.

My advice? Talk to your family doctor or your local drug & alcohol rehab center. They usually have a team of experts at their disposal to help you with your questions, and they are better equipped to evaluate your husband's reaction.
