Jurgen Rehm and Benedikt Fischer argued that the reasons for rejecting the treatment of heroin as part of therapy heroin dependence does not exist.

British scholar believes that properly organized treatment leads to a much better outcome than simply stabilizing dependence through maintenance therapy. For example, studies conducted in Scotland (UK), shows that 29.4% of the total drug addicts in the number who participated in the rehabilitation program, did not use heroin for a minimum of 90 days, compared with 3.4% of addicts who received supportive therapy methadone.
The results of another study indicate that the majority of drug addicts are waiting for assistance from specialized agencies to gain freedom from drugs. I very dangerous in this case is the use of techniques that promote conservation of dependence instead lead to its reduction, as the health care system is obliged to provide full support to a drug-dependent people in their desire to free themselves from the poisonous smell.
