Marijuana is a plant product that is smoked or eaten to produce an altered state of mind or high. Marijuana impairs thinking, learning, judgment, lung and brain development in young people, concentration, and driving. One smoke inhalation of marijuana can stay in a person’s system for up to a week; therefore, can impair driving for days after smoking. Marijuana impairs thinking for up to 48 hours after using, even though the ‘high’ can be gone after a few hours.

With the rise of medical marijuana, the perceptions that marijuana is harmless and not additive are increasing. Marijuana remains a Federal Schedule I Drug, which means that the federal government doesn’t not recognize the medicinal use of marijuana and finds that marijuana has a high potential for abuse (NRS 453.166)
