We thank Drs Hall & Carter [1] for their interest in our article [2], and appreciate their reiteration for the need for caution as deep brain stimulation (DBS) evolves. We share many of the same concerns which, as they concede, are addressed thoroughly in the Discussion. We did not enumerate every limitation of the study in the abstract, which is hardly the place to look for clarifying details.We disagree with the claim that our analysis was 'biased' towards supporting DBS. We include only data collected from clinical trials conducted at academic centers for both methadone maintenance therapy (MMT) and DBS. Thus, like any meta-analysis or clinical trial, our results may not be generalizable outside a tertiary center.At this point, we are not recommending DBS as a therapy for heroin addiction, but rather calculating the threshold it must reach to compete with MMT. A threshold success rate of 49% supports pursuing a clinical trial. We cannot assume that heroin-dependent subjects will attempt to 'subvert' the effects of DBS, nor can Hall & Carter. There is certainly a need for developing strict inclusion criteria for a trial, and perhaps previously demonstrated compliance should be one criterion.Lastly, in no way do we recommend that DBS be used for social control, nor do we imply anything of the sort in our manuscript. Any technology can be put to malicious or evil use. Our argument is aimed only at examining the merit of pursuing DBS as a therapeutic option for a disease that at present has a poor prognosis in light of the clinical therapies that are available.

OFFERING INCENTIVES TO DRUG-USING WOMEN TO TAKE UP CONTRACEPTION: THE ETHICAL AND CLINICAL ISSUESWe write in response to the paper by Jayne Lucke & Wayne Hall [1] regarding their discussion about offering incentives to drug-using women to use long-acting forms of contraception. Their premise, that cash and noncash incentives could be used in this group of women, only partly addresses many of the key ethical and clinical issues in this debate. Indeed, it is difficult to explore these ethical issues fully without addressing the many barriers experienced by this population in accessing appropriate contraception. Women with substance abuse issues report difficulties using conventional systems of care for a number of reasons, including a mistrust of health-care services, fear of forced treatment or fear of losing custody of children, guilt, denial or embarrassment regarding their substance use, stigma and the costs and difficulty of accessing services [2,3]. Other barriers these women face in accessing contraception include a belief that contraception is not needed due to impaired fertility while in drug treatment (e.g. methadone) and misinformation about different methods [4]. As it stands currently, women in specialist drug treatment needing sexual and reproductive health care are usually referred to external services, either to their general practitioners, sexual health clinics or family planning centres.A recent survey of wom...
