Health Education: Alcohol, Tobacco, and Other Drug Prevention
This domain tests drug classification, the physiology of alcohol and nicotine, accurate standard-drink and blood-alcohol reasoning, and evidence-based prevention strategies for schools. Expect quantitative items on standard drinks and qualitative items on prevention program design.
Classification and pharmacology
Stimulants (caffeine, cocaine, methamphetamine, prescription stimulants), depressants (alcohol, benzodiazepines, barbiturates), opioids (heroin, oxycodone, fentanyl - respiratory depression is the lethal effect), hallucinogens (LSD, psilocybin), cannabinoids, inhalants, and anabolic steroids. Key vocabulary: tolerance (needing more for the same effect), dependence, withdrawal, synergism (combined effect greater than the sum), antagonism, potency versus dose.
Alcohol specifics
Alcohol is a depressant. One U.S. standard drink contains 0.6 fl oz of pure ethanol: 12 oz beer at 5%, 5 oz wine at 12%, 1.5 oz distilled spirits at 40%. Binge drinking is 5+ drinks for males or 4+ for females in about two hours. Blood alcohol concentration rises with body weight (inverse), female sex, empty stomach, and faster consumption; tolerance does not lower BAC. Fetal alcohol spectrum disorders are the leading preventable cause of intellectual disability. Only time lowers BAC.
Tobacco and nicotine
Nicotine is highly addictive and reaches the brain within seconds when smoked. The federal minimum purchase age is 21. E-cigarettes deliver high nicotine doses and carry risks including e-cigarette/vaping product use-associated lung injury (EVALI).
Prevention that works
Life-skills training, refusal skills, correcting misperceived peer norms, normative feedback, policy and enforcement (no-cessation-of-supply, parent involvement), and interactive - not lecture-only - delivery. Fear-based assemblies are not evidence-based.
Worked example
A student drinks two 16 oz pours of a 7% alcohol craft beer. Ethanol = 32 oz × 0.07 = 2.24 oz. Divide by 0.6 oz per standard drink = about 3.7 standard drinks, not two. Reasoning: standard drinks normalize across beverage types; volume alone misleads because the percentage differs from the 5% reference beer.
Traps that cost marks
- Calling alcohol a stimulant because it initially relaxes inhibitions.
- Assuming a high tolerance means a lower BAC or safe driving.
- Suggesting coffee, cold showers, or food "sobers you up" - only time metabolizes ethanol.
- Treating "just say no" alone or one-shot assemblies as sufficient prevention.
