Your friend decides to smoke a cannabiscigarette, which increased his blood levelof THC to 19 ng/mL. Assuming the halflife of THC in your friend's body is about36 hours, and a blood test has a detectionlimit of 3 ng/mL, for approximately howmany days would THC still be detectablein his body? In your calculations, use 3significant digits in the continuous growthrate value.
