"These pilots suggest that community-based drug safety testing can provide, first, engagement with more diverse drug–using communities than event-based testing—in terms of demographics, drugs of choice and risk taking behaviours—and therefore potentially can be more inclusive and impactful across drug–using communities including with marginalised groups. Second, there is the potential benefit of issuing proactive alerts for substances of concern in local drug markets ahead of specific leisure events, as happened with a mis-sold ketamine analogue identified in this study. Third, community testing can benefit from accessing fixed site laboratory facilities (in this case, a university chemistry department) to complement the speed and convenience of mobile laboratories with potentially greater analytical capabilities and trialling of new technological developments.
"These benefits cannot be presumed, however. The community pilots highlighted that service design characteristics and operational variations such as venue, day of week, prior publicity and outreach activities all can influence outcomes. Moving to a neutral central building attracted larger numbers and a greater diversity of service users as well as building trust with new service user groups, with drugs outreach staff further enhancing engagement with more marginalised drug using communities."
