Cocaine Addiction

Cocaine addiction is the excessive intake of cocaine, and can result in physiological damage, lethargy, depression, or a potentially fatal overdose. The immediate craving to use more cocaine is strong and very common, because euphoric effects usually subside in most users within an hour of the last dosage, leading to serial cocaine readministrations, and prolonged, multi-dose binge use in those who are addicted. When administration stops after binge use, it is followed by a "crash", the onset of severely dysphoric mood with escalating exhaustion until sleep is achieved, which is sometimes accomplished by taking sleeping medications, or sedatives, a popular one being Seroquel. Resumption of use may occur upon awakening or may not occur for several days, but the intense euphoria of such use can, as it has in many users, produce intense craving and develop rather quickly into addiction. The risk of becoming cocaine-dependent within 2 years of first use is 5-6%; after 10 years, it's 15-16%. These are the aggregate rates for all types of use considered, i.e., smoking, snorting, injecting. Among recent-onset users, the relative rates are higher for smoking (3.4 times) and much higher for injecting (31 times). They also vary, based on other characteristics, such as gender: among recent-onset users, females are 3.3 times more likely to become addicted, compared to males; age: among recent-onset users, those who started using at ages 12 or 13 were 4 times as likely to become addicted, compared to those who started between ages 18 and 20; and race: among recent-onset users, non-Hispanic Blacks are 7 times as likely to become addicted, compared to non-Hispanic Whites. Many habitual abusers develop a transient manic-like condition similar to amphetamine psychosis and schizophrenia, whose symptoms include aggression, severe paranoia, and tactile hallucinations during binges.

Cocaine has positive reinforcement effects, which refers to the effect that certain stimuli have on behavior. Good feelings become associated with the drug, causing a frequent user to take the drug as a response to bad news or mild depression. This activation strengthens the response that was just made. If the drug was taken by a fast acting route such as injection or inhalation, the response will be the act of taking more cocaine, so the response will be reinforced. Powder cocaine, being a club drug is mostly consumed in the evening and night hours. Because cocaine is a stimulant, a user will often drink large amounts of alcohol during and after usage or smoke cannabis to dull "crash" or "come down" effects and hasten slumber. Benzodiazepines are also used for this purpose. Other drugs such as heroin and various pharmaceuticals are often used to amplify reinforcement or to minimize such negative effects, further increasing addiction potential and harmfulness.
