Abstract
A system for collecting cannabis and the psychoactive component tetrahydrocannabinol from a sample of exhaled breath is disclosed. Single or multiple exhaled breaths are conditioned by removing contaminants, and regulating flow rate and/or pressure to collect a sample of tetrahydrocannabinol for timely local or remote analysis. The cannabis detection system comprises a containment trap for removing interfering materials from the breath of the subject and a collection component for sampling components of breath introduced into the system through the containment trap for analysis to determine a presence of THC in the breath.
Claims21
A cannabis detection system for detecting THC in the breath of a subject, comprising:
- a containment trap for removing interfering materials from the breath of the subject;
- and
- a collection component for sampling components of breath introduced into the system through the containment trap for analysis to determine a presence of THC in the breath.
A method of detecting cannabis used by analyzing breath of a subject, comprising the steps of:
- removing contaminant material from the breath;
- collecting a sample of at least one component of the breath of the subject after the contaminant material has been removed therefrom;
- and
- analyzing the sample for the presence of THC.
A cannabis detection system for detecting THC in the breath of a subject, comprising:
- a mouthpiece for facilitating introduction of breath into the system by the subject;
- a non-rebreather valve that allows the subject to inhale and exhale while introducing breath into the system;
- a containment trap for removing interfering materials from the breath of the subject introduced into the system;
- a pressure regulator for regulating the pressure of the breath introduced into the system
- a flow measurement device for measuring a volumetric amount of breath introduced into the system by the subject;
- a collection component for sampling components of breath introduced into the system through the containment trap;
- and
- a sampling port for allowing access to the components sampled by the collection component to facilitate analysis of the components sampled by the collection component to determine a presence of THC in the breath.
