Lesson 3 Marijuana, Inhalants, and Steroids People who take illegal drugs are gambling with their lives. Marijuana No government agency inspects these substances, as is done with medicines, to make sure they’re safe and pure. Lesson 3 Lesson Objectives In this lesson, you’ll learn to: Analyze the harmful effects of marijuana, inhalants, steroids, and other substances. Analyze and apply strategies for avoiding the use of marijuana, inhalants, and steroids. Explain the relationship between alcohol and other drugs and other substances used by adolescents. Lesson 3 Marijuana Effects of Marijuana Marijuana is the common name for the Indian hemp plant. Studies have shown that an individual who uses marijuana is 17 times more likely to use cocaine than one who has never used marijuana. All forms of marijuana are mind altering and can damage the user’s health. When combined with other drugs and other substances, such as alcohol, marijuana can be deadly. Lesson 3 Marijuana Marijuana and Addiction As with other mood-altering drugs, marijuana raises levels of a brain chemical called dopamine, which produces a pleasurable feeling. When the drug wears off, however, the pleasure sensation stops, often dramatically. This abrupt letdown is called a crash. Marijuana contains more cancer-causing chemicals than tobacco smoke. It also interferes with the immune system, so the user becomes more susceptible to infections. Lesson 3 Marijuana The Health Risks of Marijuana Lesson 3 Marijuana Mental/Emotional Health Consequences Marijuana users experience slow mental reflexes and may suffer sudden feelings of anxiety and paranoia. The user may feel dizzy, have trouble walking, and have difficulty remembering events that just happened. Because short-term memory is adversely affected, problems at school and at work may develop. Users often experience distorted perception, loss of coordination, and trouble with thinking and problem solving. Lesson 3 Marijuana Physical Consequences For teens, marijuana poses physical risks to the reproductive organs. In males, regular use interferes with sperm production and lowers levels of testosterone, the hormone responsible for the development of adult male characteristics. Females experience the opposite effect—an increase in testosterone levels. This may result in unwanted facial hair and can lead to infertility. Lesson 3 Marijuana Risks and Consequences of Driving Under the Influence Marijuana interferes with depth perception, impairs judgment, and slows reflexes. The penalties and legal consequences of driving under the influence of any drug, including marijuana, are suspension of a driver’s license, a fine, and often a jail term. Insurance premiums are increased when the driver’s license is restored. If injury or death results from a drug-related accident, the impaired driver may face serious legal prosecution. Lesson 3 Inhalants Effects of Inhalants Most inhalants go immediately to the brain, causing damage and actually killing brain cells that will never be replaced. Inhalants include solvents and aerosols such as glues, spray paints, gasoline, and varnishes. They also include nitrates and nitrous oxides, which have medical uses. All inhalants are extremely dangerous, and many are labeled as poisons. Lesson 3 Inhalants The Health Risks of Inhalants Most inhalants depress the central nervous system and produce effects that include a glassy stare, slurred speech, and impaired judgment. Inhalant use or huffing, inhaling the fumes from aerosol cans, can cause sudden death by increasing the heart rate, resulting in cardiac arrest, or it can cause death by suffocation. Lesson 3 Anabolic-Androgenic Steroids Effects of Anabolic-Androgenic Steroids When used under a doctor’s guidance, anabolic-androgenic steroids help build muscles in patients with chronic diseases. Steroid use can cause mood swings, impaired judgment resulting from feelings of invincibility, and paranoia. Lesson 3 Anabolic-Androgenic Steroids Legal and Social Consequences of Steroid Use All steroid use other than that prescribed by a licensed physician is illegal and dangerous. Steroid users often turn to other illegal, addictive drugs to combat the side effects of steroids. If needles are shared or contaminated, steroid users run the risk of exposure to disease-causing bacteria and viruses. As drug testing for athletes becomes more prevalent, athletes who fail a drug test for steroids can face exclusion from an event, expulsion from the team, monetary fines, and jail time.
