Crack cocaine is the crystallized freebase form of cocaine, created by processing cocaine hydrochloride with baking soda or ammonia. It produces a much more intense and immediate high than powder cocaine because smoking allows the drug to reach the brain within seconds. The name "crack" comes from the crackling sound it makes when heated. Despite producing a more intense high, crack is chemically the same as powder cocaine.
Effects
Intense euphoria (rush), extreme energy, increased alertness, hypersensitivity, paranoia, anxiety, aggressive behavior, increased heart rate and blood pressure, dilated pupils, decreased appetite, rapid or irregular heartbeat
Risks & Dangers
Heart attack, stroke, seizures, respiratory failure, sudden death even with first use, severe psychological addiction, aggressive/violent behavior, paranoid psychosis, malnutrition, burns to lips/mouth/throat from hot pipe, infectious diseases from shared pipes, severe dental problems
Withdrawal Symptoms
Severe depression, extreme fatigue, increased appetite, insomnia or hypersomnia, psychomotor agitation, vivid unpleasant dreams, intense cravings that can last for months
Addiction Potential
Extremely High - Crack cocaine is one of the most addictive substances. The intense, short-lived high leads to compulsive redosing and rapid development of addiction.
Duration
Effects typically last 5-15 minutes when smoked, much shorter than powder cocaine
Legal Status
Schedule II controlled substance in the US. Illegal to possess, sell, or manufacture without authorization. Often carries harsher penalties than powder cocaine.

Mixing Crack Cocaine with alcohol can be extremely dangerous and potentially life-threatening. Combining substances increases the risk of:
- • Respiratory depression and overdose
