Cocaine Dependence - Cocaine Detox

Cocaine dependence is a psychological desire to use cocaine regularly. 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 use of cocaine creates euphoria and high amounts of energy. If taken in large, unsafe 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.

The symptoms of cocaine withdrawal (also known as comedown or crash) range from moderate to severe: dysphoria, depression, anxiety, psychological and physical weakness, pain, and compulsive cravings.

Signs and symptoms

Cocaine is a powerful stimulant known to make users feel energetic, happy, talkative, etc. In time, negative side effects include increased body temperature, irregular or rapid heart rate, high blood pressure, increased risk of heart attacks, strokes and even sudden death from cardiac arrest. Many habitual abusers develop a transient, manic-like condition similar to amphetamine psychosis and schizophrenia, whose symptoms include aggression, severe paranoia, restlessness, confusion and tactile hallucinations; which can include the feeling of insects under the skin (formication), also known as "coke bugs", during binges. Users of cocaine have also reported having thoughts of suicide, unusual weight loss, trouble maintaining relationships, and an unhealthy, pale appearance.

Withdrawal symptoms

After using cocaine on a regular basis, some users will become addicted. When the drug is discontinued immediately, the user will experience what has come to be known as a "crash" along with a number of other cocaine withdrawal symptoms, including paranoia, depression, exhaustion, anxiety, itching, mood swings, irritability, fatigue, insomnia, an intense craving for more cocaine, and in some cases nausea and vomiting. Some cocaine users also report having similar symptoms to schizophrenia patients and feel that their mind is lost. Some users also report formication: a feeling of a crawling sensation on the skin also known as "coke bugs". These symptoms can last for weeks or, in some cases, months. Even after most withdrawal symptoms dissipate most users feel the need to continue using the drug; this feeling can last for years and may peak during times of stress. About 30â€"40% of individuals with cocaine dependence will turn to other substances such as medication and alcohol after giving up cocaine. There are various medications on the market to ease cocaine withdrawal symptoms.

Risk

A study consisting of 1,081 U.S. residents who had first used cocaine within the previous 24 months was conducted. It was found that the risk of becoming dependent on cocaine within two years of first use was 5â€"6%. The risk of becoming dependent within 10 years of first use increased to 15â€"16%. These were the aggregate rates for all types of use considered, such as smoking, snorting, and injecting. Among recent-onset users individual rates of dependency were higher for smoking (3.4 times) and much higher for injecting. Women were 3.3 times more likely to become dependent, compared with men. Users who started at ages 12 or 13 were four times as likely to become dependent compared to those who started between ages 18 and 20.

However, a study of non-deviant users in Amsterdam found a "relative absence of destructive and compulsive use patterns over a ten year period" and concluded that cocaine users can and do exercise control. "Our respondents applied two basic types of controls to themselves: 1) restricting use to certain situations and to emotional states in which cocaine's effects would be most positive, and 2) limiting mode of ingestion to snorting of modest amounts of cocaine, staying below 2.5 grams a week for some, and below 0.5 grams a week for most. Nevertheless, those whose use level exceeded 2.5 grams a week all returned to lower levels".

Treatment

Therapy

Twelve-step programs such as Cocaine Anonymous (modeled on Alcoholics Anonymous) have been widely used to help those with cocaine addiction. Cognitive behavioral therapy (CBT) combined with motivational therapy (MT) have proven to be more helpful than 12 step programs in treating cocaine dependency. However, both these approaches have a fairly low success rate. Other non-pharmacological treatments such as acupuncture and hypnosis have been explored, but without conclusive results.

Medications

Numerous medications have been investigated for use in cocaine dependence, but as of 2015, none of them were considered to be effective. Anticonvulsants, such as carbamazepine, gabapentin, lamotrigine, and topiramate, do not appear to be effective as treatment. Limited evidence suggests that antipsychotics are also ineffective for treatment of cocaine dependence. Few studies have examined bupropion (a novel antidepressant) for cocaine dependence; however, trials performed thus far have not shown it to be an effective form of treatment for this purpose.

The National Institute on Drug Abuse (NIDA) of the U.S. National Institutes of Health is researching modafinil, a narcolepsy drug and mild stimulant, as a potential cocaine treatment. Ibogaine has been under investigation as a treatment for cocaine dependency and is used in clinics in Mexico, the Netherlands and Canada, but cannot be used legally in the United States. Other medications that have been investigated for this purpose include acetylcysteine, baclofen, and vanoxerine. Medications, such as phenelzine, have been used to cause an "aversion reaction" when administered with cocaine.

Epidemiology

In the United States, cocaine use results in about 5,000â€"6,000 deaths annually.

Research

Kim Janda has been working for years on a vaccination that would treat cocaine use disorders by limiting its rewarding effects.
