How long does cannabis stay in your system?

The duration cannabis remains detectable in your system varies depending on several factors, including frequency of use, dosage, and the type of test used. Here’s a breakdown of detection times for different testing methods:

Urine Tests

  • Single use: 1-3 days
  • Moderate use (4 times per week): 5-7 days
  • Chronic use (daily): 10-15 days
  • Heavy chronic use: 30+ days13

Blood Tests

  • Typically detectable for up to 12 hours
  • In chronic heavy users, up to 7 days1

Saliva Tests

  • Occasional users: Up to 24 hours
  • Chronic users: Up to 72 hours13

Hair Tests

  • Can detect THC for up to 90 days after use14

It’s important to note that these are general guidelines, and individual factors such as metabolism, body fat percentage, and hydration levels can influence detection times. THC is fat-soluble, meaning it binds to fat molecules in the body, which can prolong its presence in the system3.The potency of the cannabis consumed also plays a role. Higher doses and stronger strains with higher THC content result in more THC being absorbed into the body, potentially extending detection times1.For chronic users or those with higher body fat percentages, THC and its metabolites may be detectable for longer periods, sometimes exceeding 30 days in urine tests36.While most detection methods focus on THC and its metabolites, it’s worth noting that THC, the main psychoactive component, may only be detectable in saliva for 2-24 hours in most cases6.
