Albuterol has a half-life of a few hrs and needs to be taken multiple times per day. Exact detection time I'm not certain about but my guess would be it would be similar to clen since they are very closely related...almost identical with the major difference being the half-life. Clen is detectable for up to 5 days, Albuterol would probably fall in the same range but I'm not 100% positive.
Ephedrine is detectable for up to five days as well.
