Final answer:
The federal agents' action of seizing Marty's marijuana plants represents a supply reduction strategy, aimed at disrupting the availability of drugs. Supply reduction is one of several strategies in the broader antidrug initiative, differing from demand reduction, harm reduction, and legalization.
Step-by-step explanation:
When federal agents caught Marty illegally growing marijuana in his backyard and seized the plants, they were employing a strategy of supply reduction. This strategy is focused on reducing the availability of drugs by eliminating the production and distribution of illegal substances. It is a traditional approach within the broader "War on Drugs" initiative aimed at disrupting the drug market. Supply reduction contrasts with demand reduction, which focuses on decreasing people's desire for drugs, and harm reduction, which looks to minimize the negative consequences of drug use. Legalization involves the process of making the production, sale, and use of a substance legal, and it shifts the approach from criminal justice to regulatory management, which has been seen in some states for marijuana use.
