Crack cocaine is a powerful and illegal stimulant derived from powdered cocaine. It is processed into small, hard rocks that can be smoked, leading to a rapid and intense high. This form of cocaine is known for its addictive properties and can cause severe health issues, including heart problems and respiratory distress. The use of crack cocaine became widespread in the 1980s, particularly in urban areas. Its low cost and ease of use contributed to its popularity, but it also led to significant social and legal consequences. Efforts to combat crack cocaine use have included education, prevention programs, and law enforcement initiatives.
