Fears about passing a drug test are an unpleasant reality for pot smokers. When faced with the possibility, the first thing most people want to know is just how long weed stays in your system. Since it’s different for everyone, don’t trust anyone who says they can give you a definitive answer. But here are some facts about passing a drug test that will help give you an idea.

Urine Drug Test Detection Times

There’s a lot of outdated information on the Internet about how long THC metabolites can be detected in urine. At one time it was thought that they could be detected for as long as 90 days, but more recent information has shown that it’s actually much less than that.

Today it’s accepted that the detection period for marijuana in urine ranges from a few days to about 6 weeks. A few days if you’re an infrequent user, and up to 6 weeks if you’re a regular user. Passing a drug test when you have to give a urine sample can be problematic for two reasons: one, because it has the longest detection time, and two, because urine tests are the most common type administered.

The actual length of time weed will show up in your urine can vary widely, depending on factors like how often you smoke, the grade of bud you smoke, your individual metabolism, and your body fat percentage. For example, if you have a relatively fast metabolism and you only smoke once a month, passing a drug test naturally is possible within a few days. But if you’re a heavy smoker with a slower metabolism, expect it to realistically take anywhere from 4-6 weeks.

Passing Other Types Of Marijuana Drug Tests Besides Urine

Blood tests have a relatively short detection time for pot, at just 2-3 days for infrequent users and up to 2 weeks for regular users. And saliva tests have the shortest detection time of all, ranging from 24-hours to 1 week (with the norm being somewhere around 2-3 days).

Hair follicle tests can detect all types of drugs, but typically a hair test will only examine 90 days of prior history. There are several hair products on the market for passing a drug test, all of which have questionable reliability rates. However, the good news is that THC evidence tends to be weaker than other drug classes. Which means that you probably can’t cover up any other drug use, but you might have a chance if all you do is smoke pot.

What About Passing A Drug Test For Other Toxins?

Most recreational drugs are out of your system in less than a week, and after that they don’t show up in blood, saliva or urine tests. Barbiturates are kind of a wild card, because their detection times can vary depending on the particular drug and how long you’ve been taking it. Some are a few days, and some are a few weeks. So if you’re in the habit of using un-prescribed barbiturates, you’ll need to get on the Internet and look for specific information about the particular drug by name.

Is Passing A Drug Test Even Possible If You Have THC In Your System?

Fortunately, the overwhelming majority of drug tests administered are for either urine or saliva, both of which are entirely possible to pass. You’ll find plenty of information about passing a drug test on this website.

But if you’re wondering whether or not you might be clean already, you’re not going to find the answer on the Internet. Go to a pharmacy and buy a single-panel drug test strip, and administer it to yourself at home. Passing a drug test is too important, and that’s the only way you’re going to find out for sure exactly where you stand.
