Play it smart by reviewing your employer’s drug policy and use the information below to prevent hearing the dreaded words, “You tested positive for marijuana.”

How Long is Weed in Your Urine?

Marijuana stays in urine for approximately 3-30 days. This range is due to a few factors:

  • How much and how often you use: the more you consume, the longer THC remains in your body
  • Body fat percentage: low percentages will expel THC quicker than high percentages as THC binds to body fat
  • Hydration: drinking significant amounts of water can reduce the time THC remains in your body
  • Exercise and metabolism: exercising and increasing metabolism can reduce the time THC stays in your body
  • Biological Sex: because females have more body fat than males, it may take females longer to eliminate THC
  • Test sensitivity: some tests are more sensitive than others and may detect lower doses of THC
