Symptoms include stimulant effects such as agitation, racing heartbeat & breathing, sweating, in addition to psychostimulant effects of dilated pupils, hallucinations and delirium.
Cocaine has a significant potential to cause cardiac toxicity – elevated blood pressure, abnormal heart rhythms, chest pain, heart muscle damage, cardiorespiratory arrest and heart attack are all potential complications of cocaine use.
In addition, kidney failure, hypokalaemic paralysis, acidosis and seizures are also serious symptoms that may occur with use. Hyperthermia progressing to hyperpyrexia with the potential to cause multi-organ failure is a potential complication due to cocaine being a potent serotonin reuptake inhibitor.
Due to the caustic nature of the drug, damage to the nasal septum and rhinitis (“runny†nose) may occur. Via intravenous injection (which is strongly discouraged) pulmonary embolism, a potentially lethal condition can develop. Smoking also poses a risk, including pulmonary oedema (fluid build-up on the lungs).
