It is possible after a long period of abstinence that some of these effects may be reversed.

Testing for methamphetamines is done by either blood or urine. Hair and skin can also be tested, but urine testing is the most reliable. The drug reaches the urine in about three to five hours after use. Blood testing is very expensive but accurate and if you test positive, it is a probability that the results are correct. Federal drug testing does not allow blood tests at this time. Saliva tests are accurate, but not used very widely. Hair tests will show use even three months later. This testing is very reliable but must be done in a laboratory and is more expensive. If you have used methamphetamines there is no way to alter the test results for blood and hair. The best you could do is cause a false positive in the urine test.
