i was thinking more of the social level. By this i mean that for example for every £1 that is spent on drug treatment there is a comparitive saving of £9.50 to the community - mainly in terms of crime that does not happen (University of York) . I also wonder if people are being set up to fail by being entered into a system of treatment, abstinence and relapse when for some people long term prescribing is the answer to a less chaotic lifestyle where they are well enough to look after the kids / family, enetring some sort of education or training and even work all of which is not possible when the day has to consist of finding cash to buy drugs and then taking those drugs ( I am mainly talking about heroin here).
the way i look at is that some people are prescribed anti depressants for a long period of time and are not made to feel bad about it whereas people on methadone are made to feel they should be 'off it' as soon as possible
I am aware there are medical problems with the use of methadone but I think there must be much more negative effects with the long term use of street adultarated heroin.
the debate about wether drug treatment works has been bubbling about for a while . in 2007 drugscope issued a very interesting article looking into this argument the link is here it is well worth a read.
