Marijuana laws, Safety, and Toxicity

The Laws

Marijuana is still illegal for teens in all 50 states. Whether it’s smoked, vaped, or consumed there are lasting consequences to a youth’s academic and cognitive development. Marijuana dulls attention, memory, and learning skills; making students who use it more likely to drop out of high school or college. Long-term, repeated use can lead to addiction and usage of other drugs.

Consequences and Risks

The Office of Cannabis Management has resources for parents and young adults on laws, health effects, impaired driving, and other important topics related to cannabis. Parents and mentors: You can impact whether the young people in your life consume cannabis. Start the conversation with them early and have it often. Make sure they understand the consequences and the negative impact it can have on their growing, developing brain. Pre-teens, teens, and young people in their early 20s tend to seek out new experiences and engage in risky behaviors, like using cannabis.

Marijuana Toxicity Levels and Impacts

The CDC provides information and resources on the health effects of marijuana toxicity. Children, adults, and pets can mistake marijuana products, particularly edibles, for regular food or candy. Consuming marijuana can make children very sick. They may have problems walking or sitting up or may have a hard time breathing. Since marijuana use has been legalized in some states, accidental marijuana poisonings in children have increased, sometimes requiring visits to the emergency room or hospitalization.
