The length of time that marijuana stays in your system can vary depending on several factors, including the frequency and amount of use, your metabolism, and the sensitivity of the drug test being used.
THC, the main active ingredient in marijuana, is metabolized by the liver and then eliminated from the body through urine and feces. The metabolites of THC can be detected in drug tests for different lengths of time depending on the type of test used.
Here are some general estimates for how long marijuana can stay in your system:
• Urine tests: THC can be detected in urine for up to 30 days after heavy use, and for up to 3-4 days after occasional use.
• Blood tests: THC can be detected in blood for up to 2-7 days after use, but it can be longer for heavy users.
• Saliva tests: THC can be detected in saliva for up to 72 hours after use.
• Hair tests: THC can be detected in hair for up to 90 days after use.
It's important to note that these are just estimates, and individual results can vary based on a variety of factors.
