How long will it take to get meth out of your urine?

If you only used half a gram of meth in about 1-2 days, and you keep water flowing through your body all day (not necessarily excessive drinking, just continuous) you can probably get it out in 1-2 days. Meth will not stay in your body longer than five days, but injecting it for a long period of time might keep it for up to two weeks. drink a lot of water; hydration is key in washing it out.
