Limerick East): Methadone maintenance is one of the most successful treatment programmes for heroin addiction. Studies have shown that it is extremely difficult to fully rehabilitate persons addicted to heroin, but methadone maintenance programmes make a significant improvement in health and behaviour of such persons, with consequential benefits to them, their families and society in general. There are, in addition, considerable public health benefits, with a reduction in the risk of spreading HIV and hepatitis C. The level of drug-related crime also reduces. I am aware that reservations are expressed about methadone maintenance as a form of treatment but I am satisfied that it is a valid part of multi faceted treatment programmes.
