If you use meth one time then how long would it take for it not to show up in your blood?

Answer by  djcwoman37 (373)

A lot of factors need to be taken into consideration. For example, how fast your body can metabolize the chemicals, the kind of chemicals used, how much was used and how frequent. In general, it is possible that methamphetamine will not be detected in your system after about four days.

That's a hard question to answer because it depends on a lot of factors such as your metabolic rate and the concentrations of different chemicals in the meth and so on. It is generally accepted that meth will no longer be detectable in your system after about 4 days, in most cases.

The lasting effect of meth being in your body can be from several days to a month. How long this drug is retained depends on your body itself, how much meth you have taken, how frequent and forhow long. Remember this: "When the high goes, the drug stays."

There is a fairly short half life for meth, thus it would be out of your blood in about 72 hours.

Answer by  EmmaKitty (236)

Methamphetamine takes anywhere between 1-3 days to not show up on a blood test (as opposed to 3-5 days for a urine test). Since you only did it once, 36 hours could be time enough to test clean. But I can't state that with any certainty. Everyone is different.

Whether you do meth once or twice or even more it still takes up to 3 days for it to get out of your system.Some people say it could take up more time depending on body weight butI am not sure about that.I just know from what I have read in alot of drug and addiction books...

The answer is unsure. Sometimes it can be out of your system in one day, other cases a week, and more cases, up to three months. It depends on how much you use.
