Marijuana is a green, brown, or gray mix of dried, crumbled parts from the marijuana plant. It can be rolled up and smoked like a cigarette or cigar or smoked in a pipe. Sometimes people mix it in food or inhale it using a vaporizer.

Marijuana can cause problems with memory, learning, and behavior. Smoking it can cause some of the same coughing and breathing problems as smoking cigarettes. Some people get addicted to marijuana after using it for a while. It is more likely to happen if they use marijuana every day, or started using it when they were teenagers.

Some states have approved "medical marijuana" to ease symptoms of various health problems. The U.S. Food and Drug Administration (FDA) has not approved the marijuana plant as a medicine. However, there have been scientific studies of cannabinoids, the chemicals in marijuana. This has led to two FDA-approved medicines. They contain THC, the active ingredient in marijuana. They treat nausea caused by chemotherapy and increase appetite in patients who have severe weight loss from HIV/AIDS. Scientists are doing more research with marijuana and its ingredients to treat many diseases and conditions.

Suicide is the tenth most common cause of death in the United States. People may consider suicide when they are hopeless and can't see any other solution to their problems. Often it's related to serious depression, alcohol or substance abuse, or a major stressful event.

People who have the highest risk of suicide are white men. But women and teens report more suicide attempts. If someone talks about suicide, you should take it seriously. Urge them to get help from their doctor or the emergency room, or call the National Suicide Prevention Lifeline at 1-800-273-TALK (8255). It is available 24/7.

Therapy and medicines can help most people who have suicidal thoughts. Treating mental illnesses and substance abuse can reduce the risk of suicide.
