You may be worried about certain substances showing up on a drug test. You know that different drugs last in the human body for different amounts of time, and that this is vastly longer than the actual effects of that drug on the person who took it, but you want to know exactly how long that could be.
First and foremost, this is not that precise of a science. The length that traces of the drug last in your system depends on a lot of different variables. One of these is simply how often you use them, which means that the answer can be different for everyone. But there are some general ranges that you can expect to see.
Marijuana
If you use marijuana products, they may only affect your behavior for a few hours at most. But they can still be found for two weeks through a blood test or from 7 to 30 days in a urine test.
Cocaine
Cocaine exits a person’s system relatively quickly, as it can only be detected in a blood test for 1 to 2 days. It may show up in a urine test for 3 to 4 days.
Methamphetamine
Those who use methamphetamine can expect to see it show up in a urine test for the next 3 to 6 days. The range for a blood test is shorter, at one to three days.
Hair tests
One final thing to note is that many drugs will show up in hair tests for months after the drugs have been used. This is because hair grows very slowly, at just about a centimeter each month.
If you do find yourself facing serious drug charges, you absolutely need to know about all of the legal defense options that you have.
