The hydrochloride (HCl) salt of cocaine is by far the most commonly encountered, although the sulfate (-SO 4) and the nitrate (-NO 3) are occasionally seen.t is commonly snorted, inhaled, or injected into the veins. Mental effects may include loss of contact with reality, an intense feeling of happiness, or agitation. Physical symptoms may include a fast heart rate, sweating, and large pupils.
After cocaine has entered the body it is passed through system until it hits the liver. Once it reaches the liver it metabolizes into a substance called Benzoylecgonine. This metabolite is what is detected and causes drug tests to have a positive result for cocaine. Cocaine itself can only be detected for up to twelve hours in the blood whereas, the metabolites can be detectable for as long as 48 hours.
