Reducing the drug supply is one way to help prevent drug abuse. To counter the abundant supply of illegal drugs, laws must be enforced and strengthened against the manufacturing, selling and possessing of drugs. In addition, the message that drug use is unhealthy and unacceptable must be consistent through schools, family, media, politicians and public figures. Public education and media campaigns are powerful drug prevention tools. School systems should also adopt active and creative drug abuse prevention programs. Lastly, health professionals should receive formal training in the diagnosis and treatment of drug dependency.
