Many drug tests are urine tests. They typically only work for a few days. Some drugs can only be detected the following day. Others stay for a couple of days or, generally speaking, a week at most.
However, it is important to remember that urine tests are not the only types of tests you can take. When using hair follicle tests, they can give results for about three months, or 90 days.
Some of the drugs often searched for with these tests include:
- Other opioids
The test involves cutting your hair and testing the hair itself. They can use hair from your head or body.
The information about past drug use is within the hair itself, so there is no way to trick or fool the test. For instance, some people assume they should just wash their hair first. Others try to use styling products. Still others go in to have their hair dyed or they bleach it out. You can do all of that, but none of it is going to make the test less accurate than it would be otherwise.
If you’re facing drug charges or if you have been accused of using illegal drugs, you must know how these tests work and what evidence they can provide for a criminal case. At the same time, you need to make sure you understand all of the legal defense options that you have.
