OBJECTIVES Δ(9)-Tetrahydrocannabinol (THC) can be measured in exhaled breath by using an aerosol particle collection device. The sampling procedure is simple, non-invasive and takes only 2-3min. In the present study we measured the amount of THC in exhaled breath of cannabis users at specific time intervals up to 3h after smoking one cannabis cigarette. DESIGN AND METHODS The breath concentration-effect relationship was studied by measuring the pulse rate and the pupil diameter to assess… CONTINUE READING
