I have to take a drug test monday mourning and I smoke about 20 hits of crack on thursday will I pass
Yes, crack normally stays in the system 3 days. After 4 days, you should be clean.
After smoking, cocaine is rapidly absorbed with peak plasma concentrations occurring at about 5 minutes, versus 30-40 minutes following intranasal ingestion. Cocaine is extensively metabolized by the liver and blood enzymes with approximately one percent of the dose excreted in the urine unchanged. The major metabolite found in the urine is benzoylecgonine (25-40% of the dose), followed by ecgonine methyl ester (18-22%). Depending upon the dosage ingested, frequency of use, and metabolic variation, benzoylecgonine can remain detectable in the urine for as long as 48-96 hours post ingestion
