    Caffeine and ephedrine - Which has the longer half life?

    Basically, which one clears from the system slower?

    Actually, the two have very similar half-lives, ranging, on average, between 4-6hrs. Excretion rate of course depends on a number of factors, especially acidity levels.

    Pain.... I did some research through google and found that caffeine has a (slightly) longer half-life based on a slew of averages... so basically, on an average dose for an average adult male ephedrine will leave the blood stream faster than caffeine.

    Interesting. I believe this could be true, I crash harder on Ephedrine than caffeine is seems. Thanks again.
