Cocaine dependence is a neurological disorder that is characterized by withdrawal symptoms upon cessation from cocaine use. It also often coincides with cocaine addiction which is a biopsychosocial disorder characterized by persistent use of cocaine and/or crack despite substantial harm and adverse consequences. The Diagnostic and Statistical Manual of Mental Disorders , classifies problematic cocaine use as a "Stimulant use disorder". The International Classification of Diseases , includes "Cocaine dependence" as a classification under "Disorders due to use of cocaine”.
The use of cocaine creates euphoria and high amounts of energy. If taken in large doses, it is possible to cause mood swings, paranoia, insomnia, psychosis, high blood pressure, a fast heart rate, panic attacks, cognitive impairments and drastic changes in personality. Cocaine overdose may result in cardiovascular and brain damage, such as: constricting blood vessels in the brain, causing strokes and constricting arteries in the heart; causing heart attacks.
The symptoms of cocaine withdrawal range from moderate to severe: dysphoria, depression, anxiety, decreased libido, psychological and physical weakness, pain, and compulsive cravings.
