A community-run programme in London is training people who use drugs in queer communities to share harm reduction advice in the very spaces where sexualised drug use happens, and a new participatory evaluation suggests the model is reshaping how peer-led support can work. The programme, called Sex, Drugs, and Care for All, was developed by The Love Tank, a community interest organisation, together with Antidote, a drug and alcohol service, with funding from a London borough. Researchers published their findings in Harm Reduction Journal on 5 October 2026.
Sexualised drug use, which includes but is not limited to chemsex, can be pleasurable and empowering for those who practise it, but it also carries risks related to sexual ill-health, sexual assault, overdose and addiction. According to the study’s authors, there is a dearth of accessible and inclusive harm reduction advice and services for sexualised drug use in the United Kingdom. SDC4A was designed to fill that gap by offering an alternative to existing brick-and-mortar services and conventional outreach efforts.
The core of the programme lies in its peer mobilisers. Rather than expecting people to visit clinics or specialist services, SDC4A trains diverse cohorts of community members to impart harm reduction advice in the settings where sexualised drug use actually takes place.
The evaluation itself was participatory, rooted in critical approaches to evaluation that explore emergent impacts, process and lived experiences. The researchers conducted two focus groups with seven mobilisers and eight interviews with personnel involved in designing and implementing the programme. Because the study is qualitative and involves a small number of participants, its findings describe experiences and themes rather than measuring outcomes such as reduced overdose rates or changed drug use patterns.
One of the central themes to emerge was the importance of understanding sexualised drug use as a spectrum. Participants and programme staff framed SDU not as a single behaviour or a uniform crisis, but as a range of practices with varying levels of risk and intensity.
The evaluation also found that mobilisers are motivated by an ethics of care, and that being a mobiliser feels empowering and prideful.
In practice, mobilisers impart advice on safer drug use, but they also open up conversations about harmful use.
Another theme concerned the value of working across organisations. The collaboration between The Love Tank and Antidote, with local government funding, created new communities of practice and new possibilities for doing harm reduction work. The study’s conclusions emphasise that the value of co-developing programmes between organisations and with the community lies in strengthening this community of practice alongside the ethics of care that motivates individual mobilisers.
The evaluation did not shy away from challenges. Participants identified difficulties in reaching more marginalised populations, as well as people whose sexualised drug use is at crisis level.
The authors conclude that harm reduction programmes for sexualised drug use must be flexible and able to learn from the communities they are developed with and for, in order to address the full spectrum of SDU. As a qualitative evaluation of one London programme, the study offers a detailed picture of how a peer mobiliser model functions in practice, but it cannot establish effectiveness in reducing drug-related harms.
