Weed (THC) can stay detectable in urine for varying lengths of time depending on how frequently and how much you use it:
- For occasional or one-time users , THC metabolites are typically detectable in urine for about 3 days but can extend up to 7 days in some cases
- For moderate users (about 3-4 times per week), detection can last around 5 to 7 days
- For daily users , THC can be detected for 10 to 15 days after last use
- For heavy or chronic users (multiple times per day or long-term use), THC metabolites may remain detectable for 30 days or longer , sometimes even beyond 30 days depending on body fat and metabolism
Factors influencing detection time include metabolism, body fat, frequency of use, potency of the cannabis, hydration, and individual health
. From Reddit discussions, occasional users who barely smoke often find THC clears from their urine within about a week, especially if they stay well- hydrated, but results can vary
. Frequent or heavy users will have longer detection windows. In summary, if you are an infrequent or light user, THC is usually detectable in urine for up to about a week, but for regular or heavy users, it can remain for several weeks or even a month or more
