THC — which is the substance in marijuana that gets you “high” — sticks to CB1 receptors in the brain, causing temporary changes in how your brain processes information. Some of the effects marijuana has on driving include: - Reaction times slow down - You will find it difficult to follow moving things - Your judgment and perception of distances will be affected Even though you might think you are okay, your brain may still process information at a slower rate than you are used to. ## How long after smoking cannabis is it safe to drive? Unfortunately, there is no specific amount of time that applies to every individual. Most research indicates that the majority of the impairments associated with marijuana occur between 1 to 3 hours after smoking, although the length of impairment can vary based on several different factors. Factors That Influence How Long Impairment Lasts Include: - Dose of THC in the marijuana - Frequency of marijuana use - Level of tolerance - Method of ingestion (i.e. smoking versus eating marijuana) For someone who does not frequently smoke marijuana, the impairment can last significantly longer — often up to six hours or more. ## Guidelines For Waiting Times | **User Category** | **Waiting Time (Hours)** | | --- | --- | | Recreational User | 6 – 8 Hours | | Moderate User | 4 – 6 Hours | | Frequent User | 3 – 4 Hours | | Eating Marijuana (Any User) | 8 – 12+ Hours | ⚠️ These waiting times provide only a general guideline; they do not guarantee that an individual will be safe to drive. ## Assuming You Feel Fine Means You Are Fine To Drive Perhaps the largest misconception regarding marijuana and driving is that just because you feel fine, you are fine to get behind the wheel of your car. There are many reasons why this is not true. The most significant reason is that marijuana impairs your ability to operate a vehicle without you realizing that you are doing anything wrong. As a result, experts suggest using a waiting period to determine when it is safe for you to get behind the wheel of your car rather than relying solely on your own personal perceptions. ## Tips To Help You Make Safe And Lawful Decisions Regarding Marijuana Use And Driving If you intend to drive, please take into account the following steps that may help protect yourself from harm and help you comply with the law: - Do not operate a motor vehicle on the same day you consume a high-THC product. - Select products that contain lower levels of THC and/or balanced levels of THC and CBD. - Never combine marijuana and alcohol. - Plan ahead by arranging for a ride home prior to operating a motor vehicle. ## Why The Quality And Accuracy Of Your Products Matter All marijuana products affect the body differently.
