Safe injection sites, also known as supervised injection facilities, have been shown to be effective in reducing harm associated with drug use, such as overdose deaths and transmission of infectious diseases. Studies have found that safe injection sites can reduce overdose deaths by providing immediate medical intervention if an overdose occurs, and by offering harm reduction services such as sterile needles and other drug use equipment, as well as access to addiction treatment and other healthcare services.

However, some opponents argue that safe injection sites can encourage drug use and enable addiction. It is important to note that these sites are just one component of a comprehensive approach to drug addiction and that they do not replace the need for addiction treatment and recovery programs.
