When methadone is administered correctly, the dosage is slowly reduced over time. Additionally, staff refer patients to rehabilitative treatments in hopes of overcoming their addiction. Unfortunately, many of these clinics do not have the proper incentives because most American methadone clinics are run by for-profit companies. In fact, these companies have become major targets of investment firms due to their high profits. For example, Bain Capital, the venture capital firm founded by Mitt Romney, purchased the largest methadone company, CRC Health Group, for $723 million in 2006. Subsequently, the company received more than a thousand regulatory citations since 2009 and addicts have indicated a number Methadone is more physically addictive than heroin and as many as 25% of people do not respond physically well to methadone. In turn, numerous research supports that heroin prescriptions are a better option for that particular group. A study in the New England Journal of Medicine found that heroin addicts who were prescribed heroin, rather than methadone, were more likely to quit, stayed in treatment longer and were much less likely to use the street version of the drug. After one year, 90% of participants using heroin prescriptions were still in treatment, compared to only 54% of the methadone group. In fact, a study published by the Canadian Medical Association Journal found that heroin prescriptions are also more affordable than methadone treatments and result in less crime and less public health care. Only "hard-core" drug addicts participated in this experiment. The success of these studies has made heroin injection facilities a permanent part of the Swiss harm reduction model. These facilities are staffed by adequate health professionals, and drug users pay about 15 Swiss francs a day (about 15 US dollars), much less than the retail price. As a result, injecting facilities improve public safety by eliminating the public, huddled masses of heroin addicts and the resulting crimes and needle trading. These facilities are also a non-confrontational way to subtly reintroduce addicts into mainstream culture and extend a lifeline in hopes of finally getting them into treatment. Ethan Nadelmann, executive director of the Drug Policy Alliance, summarized some findings from the Zurich Department of Social Security. He noted that: “Heroin prescribing is feasible…The health of drug users in the program has clearly improved…Heroin itself causes very few, if any, problems when used in a controlled manner and administered under conditions hygienic". He added that drug users did not overdose, even with an unlimited supply on hand
