Crack cocaine is a form of cocaine base and a potent central nervous system stimulant. It is a controlled substance in many jurisdictions and is primarily discussed in forensic science, toxicology, pharmacology, medical research, and public-health contexts.

Its effects can occur rapidly when inhaled as smoke and may include increased alertness, energy, and euphoria. Adverse effects can include anxiety, agitation, elevated heart rate, abnormal heart rhythms, paranoia, seizures, and other potentially serious complications. Repeated exposure can result in tolerance, dependence, and substance-use disorder.

In authorized scientific research, cocaine-related compounds may be examined for their chemical characteristics, metabolism, toxicology, analytical detection, and forensic identification. Work involving controlled substances should be conducted only by appropriately authorized laboratories and qualified personnel.
