It depends on the drug. An immunoassay for TCH, for example, may show traces for up to four weeks or longer, depending on the amounts used, weight of the user, and a couple of other factors. Others vary as well, generally below that length of time. A quantitative analysis, however, will determine how much is still in the system, and can be used to determine within certain limits how long since use occurred.
THC (Marijuana) is stored in fat, and takes a long time to be released.
