Drug policy and Collective Health: necessary dialogues.

The current status of policies on illicit drugs has implications for Collective Health that need to be discussed in depth. This essay aims to explore, in light of the best evidence, the public health impact of drug policies focused on the criminalization of growing, selling, and consuming psychoactive substances. Brazil provides the context for the main analysis. The principal points addressed in this work include drugs as a social issue and the definition of the prohibitionist paradigm, evidence of the unhealthy relationship between this paradigm and the population's health, the issue of a model of care for users of psychoactive substances focused on therapeutic communities, and future paths to be explored to overcome the prohibition of illicit drugs as the principal approach to the issue. Among the main problematic elements in the repressive approach in the Brazilian context, the study highlights violence and homicides, the health impacts of incarceration and blocked access to the health system, and potential new therapies derived from currently banned psychoactive substances. As proposals for future policy changes, the study highlights decriminalization of the use, possession, and small-scale sale of drugs; the reduction of the violence and discrimination associated with policing; focus on harm reduction policies; approach to gender-related specificities; and inclusion of social variables as metrics for successful treatment of problematic drug use. In conclusion, it is relevant that the social issue and drug policy have become the object of more studies in the field of Collective Health.
