If you find yourself facing a urine test for marijuana on short notice, you're not the first to hope for a fast-acting way to help you pass it. A marijuana urinalysis aims to detect nonactive metabolites that result from our bodies breaking down tetrahydrocannabinol (THC), not the psychoactive compound itself, and this is how we can get around to beating a urine test.
While we can't vouch for the certainty that all of these methods will help you pass a urine test, we wish you luck and offer the advice of using a home drug testing kit before submitting your final sample.
1. Same-Day Body Cleansers
Many same-day “cleansers” claim that they will flush any and all traces of marijuana from your system within a matter of hours. These products work by ridding your urinary tract and bladder of THC-residual metabolites to give you a small time frame (usually about 6 hours) of clean urine before those metabolites begin to accumulate in your bladder again.
2. Natural Detoxification Products
There are many solutions and herbal supplements that claim to speed up our body's natural detoxification and cleansing processes to flush any traces of THC out of your system within a matter days. Many of these work by increasing your fluid output via sweat and urine as well as your metabolism.
You can purchase synthetic urine from a variety of sources, but it may be impossible for you to know how sophisticated the testing equipment will be (some labs have the ability to determine if urine is genuine) or how supervised you will be while giving your sample. Good news is that if you know you can get away with it, it should work like a charm.
The only way to ensure that you'll pass a urinalysis for cannabis is to abstain from your herb, edibles, and concentrates completely; it's just hard to know how long you'll need before your urine tests clean. According to the National Organization for the Reform of Marijuana Laws (NORML), just a few days are needed for occasional users while daily consumers can need up to four weeks, but factors such as diet and fluid intake, exercise habits, and personal metabolism rates play a part as well.
Rumors about how adding an adulterate (such as Visine, bleach, or ammonia) to urine once it's in the sample cup will help you pass a urinalysis for cannabis run rampant, but this method is unlikely to work. These days, labs can easily detect these substances as an irregularity in a sample as they usually change the pH levels or dilute the urine significantly.
