Are the Tests for Marijuana DUI Reliable?

Some tests have not been established as reliable for detecting impairment from eating or smoking marijuana. For example, marijuana does not cause nystagmus, which is a test that the police use. Also, the walk-and-turn test and one leg stand test were developed for alcohol impairment and not for marijuana impairment. Certain urine tests only look for inactive metabolites, which are not illegal in Arizona. And blood tests do not measure impairment, they only measure the amount found in the blood. Since tolerances and past smoking can affect impairment, there are many challenges to testing that a skilled DUI lawyer can raise. The Behan Law Group lawyers have the scientific knowledge and courtroom training to be able to defeat the tests. Call 520-220-5047 for more information.
