How long will marijuana stay in MY system?
Since you only did it once and aren’t a habitual user, I wouldn’t expect it to stay for more than a few days. (Keep in mind that the tests do allow for small amounts of a drug in your system anyway- this isn’t to encourage occasional use, but to avoid false positives due to people accidentally inhaling smoke or similar circumstances.) You’re only really in trouble if your job uses hair tests, since your hair records use as far back as the hair is long. However, they usually cut the hair sample into sections to figure out when drug use occurred, and they tend to let it go if it was over 30 days ago.
