 Critics of heroin maintenance programmes object to the high costs of providing heroin to users.The British heroin study cost the British government £15,000 per participant per year, roughly equivalent to average heroin user's expense of £15,600 per year.Drug Free Australia contrast these ongoing maintenance costs with Sweden's investment in, and commitment to, a drug-free society where a policy of compulsory rehabilitation of drug addicts is integral, which has yielded the one of the lowest reported illicit drug use levels in the developed world, a model in which successfully rehabilitated users present no further maintenance costs to their community, as well as reduced ongoing health care costs.
