Commonly Abused Drugs
Health 10Ms. Meade
Drug Categories
Stimulants: increases brain activity Depressants: slows systems down Hallucinogens: acts upon the mind Analgesics: pain killing effects Most commonly abused Drug:
Alcohol Most commonly abused Illegal
Drug: Marijuana
Marijuana
It is a hallucinogen; the chemical THC causes the distortion
Few young people use other drugs without first trying marijuana User will turn to stronger drugs if not getting the
high they want Short Term Effects: increased heart rate, sensory
distortion, panic/anxiety, poor coordination, decreased reaction time, problems with memory and learning
Long Term Effects: decreased immunity, mood changes, growth disorders, respiratory problems, decreased ability to learn and maintain focus
Marijuana
Marijuana smoke does contain carcinogens that will irritate the lungs
Contains 50-70 percent more carcinogenic hydrocarbons than tobacco smoke.
Marijuana users usually inhale more deeply and hold their breath longer than tobacco smokers do, which further increases lungs' exposure to carcinogenic smoke
Marijuana smokers show dysregulated growth of epithelial cells in their lung tissue which could lead to cancer Source: National Institute of Drug Abuse, National
Institute of Health
More on Marijuana
Medical marijuana may be useful in promoting appetite for people with HIV related anorexia, can manage nausea and help relieve pain
A synthetic form of the active ingredient in marijuana is approved by the FDA for treating HIV-related weight loss and for managing nausea associated with the use of chemotherapy.

Offers to the debate; should it be legalized? It is in CO and WA state.
Is Marijuana Addictive?
Most people who smoke marijuana smoke it only occasionally. A small minority of Americans - less than 1 percent - smoke marijuana on a daily basis. An even smaller minority develop a dependence on marijuana. Some people who smoke marijuana heavily and frequently stop without difficulty. Others seek help from drug treatment professionals.
Marijuana does not cause physical dependence. If people experience withdrawal symptoms at all, they are remarkably mild.
It can lead to addictive behaviors, like compulsive drug seeking and abuse despite its known harmful effects.
Alcohol
Depressant; slows vital functions Alcohol is more harmful to teens because
brains are still developing; drinking alcohol during this critical development can lead to lifelong damage in brain function (memory, motor skills, and coordination)
When mixed with other drug use: increased effect on CNS of both drugs because both
are competing for enzymes to be metabolized drug is in system longer Increased risk of harmful side effects,
unpredictability
Alcohol
Short Term Effects Slurred speech Vomiting Headaches Drowsiness Vision, hearing
impaired Balance and
coordination Impaired judgment

injuries Increased blood
pressure Nerve, brain and
liver damage (disease)

similar to those of cocaine but longer lasting.
Can cause erratic, violent behavior among its users.
