Cocaine dependence is a neurological disorder that is characterized by withdrawal symptoms upon cessation from cocaine use. [1] 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.
In some cases these substance-induced psychiatric disorders can persist long after detoxification from amphetamine, cocaine, opioid, and alcohol use, causing prolonged psychosis, anxiety or depression. A protracted withdrawal syndrome can occur with symptoms persisting for months to years after cessation of substance use.
Cocaine is a relatively "balanced" inhibitor, although facilitation of dopaminergic neurotransmission is what has been linked to the reinforcing and addictive effects. In addition, cocaine has some serious limitations in terms of its cardiotoxicity [188] due to its local anesthetic activity. Thousands of cocaine users are admitted to emergency ...
This also prevents the cocaine from crossing the blood–brain barrier, negating the euphoric high and rewarding effect of cocaine caused from stimulation of dopamine release in the mesolimbic reward pathway. The vaccine does not affect the user's "desire" for cocaine—only the physical effects of the drug. [69]
Levamisole has become a common additive to illicit cocaine. It is thought to intensify the "high" by releasing dopamine in the brain, acts as a bulking agent, and is a difficult adulterant to recognize. Potential risks of levamisole-laced cocaine include neutropenia, agranulocytosis, arthralgias, retiform purpura, skin necrosis, and fever.
Low energy is one of the most common symptoms of testosterone deficiency. Affected men often find that they need to nap during the day just to stay functional. ... neurotransmitters in the brain ...
Cocaine addiction results from complex molecular changes in the brain following multiple exposures to cocaine. [16] Dynorphins have been shown to be an important part of this process. Although a single exposure to cocaine does not affect brain dynorphin levels, repeated exposures to the drug increases dynorphin concentrations in the striatum ...
The neurotransmitters affected by cocaine are involved in the development of the fetus's brain, [29] so the drug may affect fetal development directly by altering the development of the brain's monoaminergic system. [31] The most important way cocaine affects fetal development is by binding to dopamine receptors. [11]
