The guide first advises African-American parents that younger African-American teens (eighth grade) are catching up to White teens in their use of marijuana (13 percent compared to 14.5 percent). Since research has shown that teens who learn about the risks of drug use from their parents or caregivers are less likely to use drugs than those who have no parental guidance, this guide instructs parents in the dangers of frequent, long-term marijuana use (adverse effects on memory, attention span, and learning ability, as well as harms to physical health and driving performance). Parents are also informed of the adverse effects of alcohol use, ecstasy, methamphetamine, inhalants, prescription and over-the counter drugs, and anabolic steroids. This review of various drugs and their adverse effects is followed by suggestions for parents in preventing their children's use of drugs. Suggestions include opening lines of communication about drugs; creating an environment that combines words with action; seeking help and support from relatives, friends, and neighbors; guarding against messages that encourage drug use; and what to do if drug use by a child is suspected. The latter discussion lists some warning signs of drug use. The guide also suggests where parents can receive assistance in helping their children avoid or stop drug use.
