The ‘drug policy ratchet’: why do sanctions for new
psychoactive drugs typically only go up?

ABSTRACT

It has been much more common for drugs to be subjected to tighter rather than looser control as drugs and evidence
about their effects have has emerged. We argue that there is in place a drug policy ratchet which subjects new
psychoactive substances (NPS) to increasing control through the continuation of historical patterns that involve the
attribution to emerging drugs of guilt by three different kinds of association: guilt by deviant association; guilt by
lunatic association; and guilt by molecular association. We use our contemporary ethnographic experience of drug
policy-making to show how these processes continue to be applied to policy on NPS, alongside selective, narrative use
of evidence and the ‘silent silencing’ by absorption of the concept of evidence-based policy. We show that the drug
policy ratchet cannot be justified as an example of the precautionary principle in action, as this principle is itself not
rationally justified. We conclude that recognition of the drug policy ratchet and its mechanisms may help researchers
and policy-makers to improve regulation of NPS.

Keywords           Novel psychoactives, policy, drug.
