I took two puffs off a joint 3 months ago. I was wondering, would I test positive with a hair sample? Other than 3 months ago, I have not smoked in over 5 yrs. Please help

You should not test positive for cannabis under the circumstances you explain.

Research provides that hair is a very poor matrix for detecting cannabis use. THC/COOH simply does not incorporate into hair as other drugs do. (see Auwater, 2010 or Musshoff & Madea, 2006)

Thank you!!
