This information is based on thousands of drug test results that marijuana users have submitted to us. This is a clear cut analysis of whether or not detox products have a beneficial impact on the probability of passing a drug test regardless of a person’s smoking habits or physical measurements.

Detox Potion vs. Water Dilution

Overall, two thirds of marijuana users do not tamper their urine when providing a sample. This results in a 31% passing rate. The average time of passing was 18.1 days with a standard deviation of 10.3.

Approximately 9% of the people who submitted their THC drug test results claimed to have used a detox product. This includes those that also diluted their urine in conjunction with using a detox product. Of these people, 42% passed. The average time of passing was 13.8 days with a standard deviation of 6.1.

The remaining 25% of the population claim to have attempted diluting their urine. Of these people, 46% passed. The average time of passing was 14.4 days with a standard deviation of 5.9.

Urine Test Pass/Fail Rates by Type

The Verdict:

People who dilute or “detoxify” their urine will have a better chance of passing a marijuana drug test. However, at the granular level, it appears that Diluting methods produce slightly better passing results than Detox products. This may be because some detoxification products fail to explicitly tell the user to drink a few extra glasses of water. Also, some labs test for adulterants and detox products.
