Here?s how long different ***** stay in your system
http://img-s-msn-com.akamaized.net/t...6&q=60&o=f&l=fContrary to what many advertised drug tests might promise, **t all substances leave their telltale chemical signature in the body for the same amount of time. The moment we take a drug — whether we s**rt, *****, or swallow it — our bodies begin to break it down. In the process, metabolites, or byproducts, of the drug are produced, which can linger in our blood, urine (and even in our hair) for long after the initial effects of the drug are felt. Traces of these metabolites are what drug testers look for, since they're a good indication that someone has actually used a drug rather than merely come into accidental contact with it. And while hair-based drug tests are fairly accurate, tests of blood and urine are simply unable to detect the vast majority of *****, so long as you haven't used for about a week. Heroin, for example, is generally undetectable in urine after three to five days. As the chart below shows, traces of ***** like LSD, morphine, heroin, amphetamines, and ******* all remain in the blood for just 12 hours or less: Dragan Radova**vic/Business Insider For urine, the window of detectibility is a little bit wider — roughly three to six days for LSD, MDMA, and morphine, for example — and up to 30 days for marijuana: Dragan Radova**vic/Business Insider Hair-based drug tests are the most accurate, as the chart below shows, since traces of everything from ******* to morphine can remain in the follicle for up to 90 days: Dragan Radova**vic/Business Insider **W WATCH: This is how long ***** actually stay in your system
