Introduction Alcohol and drug abuse is one of the major health and social challenges faced by a number of European countries such as United Kingdom and the United States of America. Prolonged use of drugs and alcohol usually results into drug addiction, which has severe effects on the health of the drug user. For instance, drug addicts often suffer from intense and irrepressible craving for drugs despite the repercussions. Most of the European countries like UK and America have adopted health policies intended to reduce drug abuse and achieve harm reduction. Harm reduction involves lessening the risks associated with using contaminated drug injection equipment. This paper examines some of the approaches adopted by the European nations and USA government in an attempt to reduce drug and alcohol abuse. Some of the initiatives include needle exchange and methadone maintenance. Needle Exchange The needle exchange program is an initiative that aims at reducing the harm associated with sharing needles and syringes among injection drug users (IDUs) whereby the IDUs get a chance to acquire hypodermic needles, as well as, injection equipment at a subsidized cost or free of charge. In some instances, the injection drug users are usually required to submit used needles to acquire an equivalent amount of new injection equipment. The needle exchange program also aims at reducing the rate of improper disposal of used drug injection equipment. Other services and materials provided by the needle exchange program include HIV and Hepatitis C testing, guidance and counseling, needle containers, and alcohol swabs. Proponents of harm reduction “believe that the needle exchange program provides a social benefit in reducing health costs”. For instance, the needle and syringe exchange program has helped to reduce the rate of HIV infection among the injection drug users in the UK, which is the pioneer of needle and syringe exchange program. Through the exchange programs, nurses are able to share information with the IDUs about HIV infection, thereby helping to prevent physical transmission of HIV. The realization of positive results in the use of needle exchange has promoted its spread to other European countries. Additionally the supporters of the exchange programs argue that the needle exchange program not only protect the injection drug users but also their families and relatives. Despite the benefits associated with needle exchange programs, there are also critics who have given various opposing opinions. For instance, opponents of the needle exchange program view the initiative as a waste of money because it promotes the use of drugs at the expense of spreading the massage of drug abstinence. Additionally, the critics believe that the needle exchange initiative promotes drug dealings because the IDUs get a chance to acquire extra injection equipment, which they can sell and use the income to purchase more drugs. Therefore, as much as the needle exchange program helps in reducing the risks associated with sharing drug injection needles, it also promotes continuous use of the drugs, thereby posing more challenge to the fight against drug abuse.
