Neurological complications due to the use of illicit drugs: a mini review

Abstract

In this paper, it is approached the neurological complications caused by the use of illicit drugs, such as LSD, Crack, Cocaine and Marijuana. These illicit drugs are used recreationally, but they are closely related to signals and symptoms many times unexplained. Many of these reactions involve the neurological system, causing common and known complications, which are present in the use of all the drugs discussed here, like visual illusions, paranoia, psychosis, hallucination, anxiety and euphoria, for instance. However, more uncommon and serious complications need special treatment for quickly actions or patient instructions, such as seizures, strokes, encephalopathies, cognitive deficits, worsening of verbal fluency and attention. In the specific case of the LSD use, the patient may present flashbacks even after the end of the drug effect.
