By Ethan Anderson| Reviewed by Olivia Bennett, Standards & Fact-Checking Lead| Updated July 26, 2026|2 min read| Fact-checked

Crack cocaine, commonly called crack, is a smokeable freebase form of cocaine. It is a powerful stimulant associated with a rapid, short-lived high and a high risk of dependence and other harms. The drug is typically sold as small rocks or crystals and is widely recognized as highly addictive and harmful.

Definition

Crack cocaine is the freebase form of cocaine and is usually smoked rather than snorted or injected. It is a stimulant drug derived from powdered cocaine.

Production and appearance

Crack is produced by processing cocaine hydrochloride with water and an alkali such as baking soda or ammonia, then heating the mixture until a solid forms. The finished drug typically appears as small white or off-white rocks or crystals.

Effects and risks

Because it is smoked, crack reaches the brain very quickly and produces a strong, short-lived euphoric effect. It is associated with high addiction potential and serious health risks.

Crack cocaine is illegal in many jurisdictions, including Canada, where possession and trafficking are criminal offences under controlled substances law.
