Even if you live in a state that's legalized marijuana use, you can still be tested for it. Even if your employer has accepted its use in off-work hours, you can still be fired if you fail a drug test for marijuana. This is because federal employment law always trumps state law, and marijuana is still firmly classified as a Schedule I controlled substance at the federal level.
With all this in mind, if you're a user of marijuana, whether medicinally or recreationally, it's good to know what you need to do before drug tests. Knowing how to perform the best cleanse before a drug test for marijuana is important, but this may vary depending on your circumstances.
Quick detox solutions
If you have limited time to detox, or simply don't want to, the best cleanse before a drug test for marijuana will probably be a same-day solution. While you can't expect to be completely clean of weed in a few hours, there are detox pills and detox drinks that can work wonders for urine drug tests.
Both of these products work by forcing your urinary system into overdrive. This helps your body to flush out toxins faster than the kidneys can reintroduce them into your urine. These products are also fortified with ingredients like creatine and B-vitamins, which help to preserve the natural state of your urine. This avoids failing the adulterant test, which can be a problem with simple dilution methods.
While urine drug tests can be terrible for marijuana users, saliva tests can still cause problems in certain circumstances. Many people keep a small bottle of special mouthwash just in case it's needed.
Long-term solutions
If you class yourself as an occasional user, or if you just want to get clean for good, a full detox may be the best cleanse before a drug test for marijuana. You will need time, however, so make sure you can realistically reach your goal. If you have any doubts, get one of the above emergency detoxes as backup.
As an occasional user, you can probably expect to be clean enough for a urinary analysis in about 10 days. A good way to kick start the process is by starting a weeklong marijuana detox program, preferably one that also includes lifestyle changes. It could take a little longer of course, especially if you're not as "occasional" a user as you think you are.
If you've been a habitual user for a while, you probably have a mountain to climb, even with an extensive cleansing program. But hey, nothing worthwhile is easy. It's hard to predict when a heavy weed user will be clean enough for a urine drug test, because there are so many factors at play, such as frequency and duration of use, amount of body fat, metabolism, and lifestyle. It may be a few weeks, or it might be a case of months. Just take it one day at a time, remember why you're doing it, and monitor your progress.
