[Discussion from drug site] Although cocaine withdrawal does not typically have visible physical symptoms like “the shakes” and vomiting that are common with heroin or alcohol withdrawal, the level of depression, lack of pleasure, and craving caused by cocaine withdrawal equals or surpasses what is experienced with most other withdrawal symptoms. The good news is that cocaine withdrawal symptoms can disappear completely over time. The bad news, however, is twofold. First, if the abuse has been chronic, various symptoms such as depression and craving can actually last for months. …
To understand why discontinuing cocaine use leads to agitation and other unpleasant withdrawal symptoms, it is necessary to briefly discuss the relationship between dopamine and cocaine. Dopamine is one of the brain’s natural “pleasure” neurochemicals. Cocaine abuse interferes with the reabsorption of dopamine, thus leading to a surplus of dopamine in the brain.
