The body quickly absorbs and metabolizes codeine narcotics.So for most standard blood or urine screens, codeine will be detectable for 1-2 days. However, codeine is detectable in hair for longer periods of time. More here on the length of time codeine stays in your system, plus how you can get addicted to codeine.ue to its short half-life, codeine doesnât stay in the blood long-term. In fact, codeine will typically fall beneath detectable levels after a day. Blood tests will probably only be ordered in situations requiring medical treatment for potential overdose or other adverse effects.
A single dose of cocaine can be detected in the blood as soon as even after a few minutes from intake to around five to six hours later. Benzoylecgonine has a half-life of around 6 to 7 hours. This would mean that this cocaine metabolite is still present in the urine after about 72 hours.ocaine is estimated to be in the system for around 72 hours since its initial intake. [6]. However, drug tests are designed to detect the metabolite of cocaine, benzylecgonine. When cocaine is metabolized in the body it undergoes hydrolysis.
