The Science of Cocaine

Cocaine is one of the most powerful and addictive stimulants known. Its effects on the brain, body, and behaviour have shaped centuries of use — from ancient ceremonial practices to today’s global drug epidemics.

In this 8-part series, we unpack the science of cocaine in clear, accessible language. Drawing on neuroscience, clinical evidence, and real-world experience, this course explains how cocaine works, why it is so addictive, and what happens during use, dependence, and recovery.

This is not sensationalism or scare tactics — it’s grounded, factual education designed to help people understand cocaine beyond myths and headlines.
