How long does codeine phosphate stay in your system.

4-6 hours half life: Is the clinical effect but may stay in your system for longer depending on your physiology, may test positive for a few days at most if that is what you are concerned about

4-6 hours: But the breakdown products can be detected for a number of days after so may show up as opiates on a drug test. Dont know if this is a concern for you or not.

Max 2 days: 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.
