how long does it take for cocaine to not show up in urine

Cocaine and its primary metabolite, benzoylecgonine, typically become undetectable in urine 2-4 days after last use for occasional users.

Detection Windows

Factors like frequency of use, dosage, metabolism, age, liver/kidney function, hydration, and body fat influence clearance times.

• Single use : Often clears in 24-72 hours.

• Occasional/moderate use : 2-4 days.

• Chronic/heavy use : Up to 10-14 days or longer.

Benzoylecgonine (tested for, not cocaine itself) has a ~6-12 hour half- life but lingers due to accumulation.

Key Factors Table

Factor| Impact on Detection Time 13
---|---
Frequency| Heavy users: 2 weeks+; light: 2-4 days
Dosage| Higher doses extend window
Metabolism| Faster metabolism shortens time
Hydration/pH| Dilute urine may delay; acidic speeds clearance
Body fat| Fat-soluble metabolites store longer

Testing Context

Standard urine tests (e.g., employment, legal) cutoff is 150-300 ng/mL benzoylecgonine; sensitive GC-MS confirms longer. No reliable home methods to speed clearance—myths like bleach harm kidneys.

Health Note

Cocaine risks addiction, heart issues, stroke. If facing tests or use concerns, seek professional help like SAMHSA hotline.

TL;DR : 2-4 days typical; varies widely by use pattern.
