What is a potential health complication from using cocaine?

Seizures are a recognized potential health complication associated with cocaine use due to its stimulant effects on the central nervous system. Cocaine can significantly increase neuronal activity, leading to an increased risk of seizures, particularly in high doses or when used in combination with other substances. The increased stimulation of the brain can disrupt the normal electrical flow, resulting in convulsions or seizures as a serious adverse effect. This risk is especially notable in users who may have underlying health issues, are inexperienced with the drug, or have consumed a substantial quantity.

While nosebleeds, chest pain, and fatigue may also be associated with cocaine use—due to its effects on blood vessels, the heart, and overall physical condition—seizures represent a more acute and immediate neurological emergency that can result from the drug's influence on brain chemistry.
