What sensation is commonly associated with alcohol withdrawal and cocaine addiction?

The sensation commonly associated with alcohol withdrawal and cocaine addiction is formications, which refers to the feeling of insects crawling on or under the skin. This tactile hallucination is particularly prevalent in individuals experiencing withdrawal from these substances. In the context of alcohol withdrawal, it typically arises when the body is adjusting to the absence of alcohol after prolonged use, leading to a variety of neurological symptoms. Similarly, cocaine addiction can produce formications due to the drug's stimulating effects on the central nervous system, resulting in heightened sensitivity and paranoia.

Formications are often a part of the withdrawal and intoxication experiences, making them an important clinical consideration in treating patients with a history of alcohol use disorder or cocaine dependence. This symptom exemplifies the complex interplay between substance use, withdrawal, and sensory perception, highlighting the need for comprehensive care in managing such conditions.
