Final answer:
Decriminalization of drugs typically involves relaxing enforcement on existing laws, shifting focus from law enforcement to public health approaches and generating tax revenue.
Step-by-step explanation:
The decriminalization of some drugs involves C) Relaxing enforcement on existing laws. Decriminalization typically means that criminal penalties for certain drug offenses are reduced or eliminated, although the activities might remain technically illegal.
This is in contrast to legalization, which removes all legal prohibitions against certain drugs. The approach of decriminalization can lead to reduced costs related to enforcement, and it often aims to handle drug use more as a public health issue than a criminal one. States that have decriminalized or legalized marijuana, for instance, often see a shift in resources from law enforcement to regulation and tax revenue generation, as well as harm reduction strategies like treatment and education.
