how long do you have to stay clean to pass a drug test
Many people who do not use marijuana often can pass a UA just four days after using a small amount of marijuana one time. While some people may test positive more than 30 days after using. In general, you will be able to pass a urine drug test between 4 and 30 days after the last time you used marijuana.If you are not sure, buy a home drug test and check yourself. In most cases you will pass within 20 days.HC is usually detectable in drug tests from 3 to 10 days. Some heavy users could (exceptionally, and using low cutoff levels) produce positive tests for up to a few months after ceasing cannabis use, as this period varies greatly according to metabolism, quantity, frequency of use and degree of sensibility tested.
