How Long Does Marijuana Stay In The System?

I have not smoked marijuana in six months until 7 days ago I had a few puffs of some low grade marijuana. I took two home test one from Walgreens one from walmart. I took a urine test today for a job with a 50ng level cut off. Should I expect to pass? Im 130 pounds and skinny. I consume more than adverage alcohol so I urinate frequently

Hi Dear,

Welcome to HCM.

Understanding your concern.

As per your query you had marijuana a week ago and you underwent test one week later, detection of marijuana depends on many factors such as drug potency, tolerance, fluid intake at time of test, method and frequency of marijuana use and body metabolism.As for being detectable in a drug test, well this depends on the type of drug test. Urine test will detect up to a month prior but a blood test will show positive you had marijuana in the last 6 months. Marijuana usually detected in urine up to 48 to 72 hours. If you have not taken it since 1 week then it is less likely that it will detect in body.Marijuana metabolites are stored in fat tissue so those users who are overweight will probably take longer to clear the drug. So you need not to worry about anything. Your test will be okay.

Hope your concern has been resolved.

Best Wishes,
Dr. Harry Maheshwari
