In Arizona, it is against the law to drive while under the influence of drugs or alcohol. Routinely, clients facing Arizona DUI charges are surprised to see that their blood or breath contained as much of a substance as the test results indicate. Thus, this post is dedicated to informing motorists about the length of time that many of the most common drugs stay in the human body. To start, it is important to note that alcohol is the only drug that police can detect through a breath test.
Thus, if police officers suspect someone of driving under the influence of alcohol, they may ask the driver to take a breath test. However, if police suspect someone is driving under the influence of drugs, they will most often take a blood test. Blood tests will detect both drugs and alcohol but breath tests will only detect alcohol.
The next critical fact to keep in mind is that someone can be found guilty of driving under the influence of prescribed medication. Occasionally, therapeutic doses of some prescription medications will not put someone in jeopardy. However, certain prescribed medications, if found in sufficient levels, can result in a DUI conviction.
