CERPSA is led by a team of policy researchers, clinicians, and educators who share a common goal: Improving the way pain is treated and drugs are controlled so that they safely reach the people that need them.
As a science-based nonprofit, we believe that there are good public health reasons for controlling drugs whether antibiotics, prescription opioids, or even medical cannabis. Consequently, the answer is not the elimination of drug controls, only their dramatic improvement so that they are more effective in ensuring access and preventing abuse. Governments rarely determine if the policies they create actually work and how they can be improved. But with your support, we can change that --- and improve the lives of millions of people throughout the state, nation, and world.
