Onset of Drug Effect(s): The primary chemical in marijuana, THC, enters the bloodstream from eating or smoking marijuana (Cannabis sativa). Effects peak within 30 minutes of ingestion and residual effects can last up to 3 hours. Chemicals from marijuana remain in the body for much longer, including several weeks, depending on amount and potency of the marijuana used.
The effects vary from person to person depending on how strong the marijuana is, how it is taken (mode of administration), and whether other drugs are taken in combination.
Drug Action(s): Acute effects on the mind and body include:
- Increased heart rate (average of 29 beats per minute MORE)
- Dryness of eyes and mouth
- Hypothalamus stimulation resulting in increased hunger (“munchies”)
- Disruption of coordination
- Distortion of thinking, perception, and problem solving
- Disturbed memory and learning processes
- Anxiety and paranoia are not uncommon and full blown panic attacks have been reported
Long terms effects on the mind and body include:
- Health issues similar to those faced by cigarette smokers: bronchitis, emphysema, cancer and heart problems (1 marijuana joint = 5 cigarettes)
- Delay of puberty and reduced sperm production in males; disrupted menstrual cycle and discharge of eggs from the ovaries in females. Pregnant women may miscarry; babies may be stillborn, have lower birth weight, or have nervous system disorders such as learning problems
- Damage to immunological system resulting in longer times to recover from disease
- Amotivational syndrome: one avoids doing the tasks he/she doesn’t want to do but must
- Onset or relapse of schizophrenia and depression in predisposed people

Debate continues on whether marijuana is a gateway drug. Former users have substantiated psychological dependence and physical withdrawal symptoms; and animal studies suggest physical dependence.
