Manipulate Drug Tests
In most countries the manipulation of a official drug test by the accused is illegal. Regularly it's not easy either.
Depending on the type of test there are some possibilities. Cutting your hair for example or using strong shampoos to avoid hair tests. But what then? The officials will just use another method.
The manipulation of blood or urine tests is more promising. Sport, sauna etc. are ways to influence your blood test results. Drinking very much water can be a way to rinse and thin concentrations.
There are products and drugs promising to help with drug tests. They should be avoided because they can be dangerous - also they may be detected too.
Urine tests are likely to be the easiest to manipulate if you manage to smuggle clean or artificial urine in the test tube. Clean Urin is such a product used by some people. Many quick tests can't detect that it is no real urine and provide clean results. But there are some factors requiring strong nerves, skills and luck. It has to have the right temperature and the investigators mustn't watch to closely.
