How Long Does Crack Cocaine Stay In Your Urine? These tests often look for unchanged cocaine, crack, and benzoylecgonine, cocaine and crack’s most prominent metabolite.Įxcessive use of crack may increase your chances of testing positive for longer times after the last dose.
Drug Testing For Crackĭrug tests try to detect various types of substance use, including cocaine use.
These are mostly formed in the liver, where enzymes break down cocaine or crack. Smoking crack creates its own unique metabolite, anhydroecgonine methyl ester (AEME). Crack and cocaine share many of the same metabolites because crack is a derivative of cocaine.Ĭocaine metabolites include benzoylecgonine, norcocaine, and ecgonine methyl ester (EME). Metabolites are the parts of drugs that stay in the body as the substance breaks down or metabolizes. Several factors, such as body fat, diet, frequency of use, and drug tolerance can affect elimination times. This means crack is likely to leave a person’s system after about 3 to 7.5 hours after last use. The half-life of cocaine and all its forms, including crack, is between 40 to 90 minutes.Īfter about 5 half-life cycles, most drugs are almost completely eliminated from the body. Half-life is the amount of time it takes for a substance to reach 50% of its maximum concentration in the body after it’s ingested. Most drug tests can find out if you have used crack in the past 2 to 4 days, while some can check the past 90 days for crack use. However, crack metabolites can be picked up by drug tests for even longer periods of time. However, crack cocaine can stay in your system for a much longer length of time, or anywhere between 3 to 7.5 hours after last use. The effects of crack cocaine last for about 5 to 10 minutes.
