How does Marijuana work?

Marijuana contains chemicals that work by binding to specific sites in the brain and on the nerves.

Are there safety concerns?

Marijuana seems unsafe when taken by mouth or smoked. Use of marijuana can cause dry mouth, nausea, vomiting, red eyes, heart and blood pressure problems, lung problems, impaired mental functioning, panic reactions, hallucinations, flashbacks, depression, and sexual problems.

Marijuana is classified as an illegal substance. Marijuana does, however, contain dronabinol (Marinol), a substance that is FDA-approved for specific uses.

Do not use marijuana if:
  • You are pregnant or breast-feeding.
  • You have heart problems or hypertension (high blood pressure).
  • You have lung problems.
  • You have seizures (epilepsy).
  • You have immune system problems.
  • You are scheduled for surgery in the next two weeks. Marijuana might cause excessive sedation if combined with medications used during and after surgery.
