Anyone know how long Ephedrine is detectable? I know the half life is like 3 hours.

the half-life varies from 3-6 hours depending upon urine pH. i don't know what the exact concentration cutoff in urine is for a positive result but it is usually safe to say that after 7 half-lives the drug should be almost all gone from your system. therefore, anywhere from 21-42 hours. the exact time depends on how much you use, how long, and what the exact concentration cutoff is for the drug.
