Final answer:
The War On Drugs strategies adopted by Congress did not include increased treatment and prevention of substance abuse; instead, they focused on criminalization, mandatory sentences, and securing borders.
Step-by-step explanation:
The strategy that was not one of the War On Drugs strategies adopted by Congress is A. Increased treatment and prevention of substance abuse. While the War On Drugs included various approaches to combat drug use and trafficking, the main strategies emphasized by Congress during this era were: B. Criminalizing the possession and/or sale of drugs, C. Requiring mandatory prison sentences, and D. Funding to secure the borders from drugs coming into the US.
The mandatory prison sentences and the emphasis on law enforcement over treatment and prevention are particularly evident in policies such as the Anti-Drug Abuse Act of 1986, which targeted crack cocaine with severe minimum sentencing guidelines. These policies, along with the militarization of local police forces and tactics like civil forfeiture, focused on harsh punitive measures rather than addressing the root causes of substance abuse such as poverty and lack of job training.
Indeed, rather than increasing support for treatment and prevention, the federal response to the drug crisis often resulted in increased incarceration, especially within minority communities, and a surge in the prison population, primarily due to the mandatory minimum sentences and three strikes laws.
