How long does one splif stay in your system?

The duration that THC from a spliff stays in your system can vary based on several factors, including frequency of use, metabolism, and body fat percentage. Generally, THC can be detected in urine for up to 30 days for regular users, while occasional users might clear it in a few days to a week. Blood tests typically detect THC for 1 to 3 days, while hair tests can show usage for up to 90 days. Individual variations play a significant role in these time frames.
