cannabis_dryTetrahydrocannabinol (THC) and Tetrahydrocannabinolic acid (THCA) are the active components of cannabis plants. The plant produces both THCA and THC which can be both detected in the plant samples. During smoking, at elevated temperature THCA loses acidic group and turns into THC which is inhaled by smoker as fume. Because THC and THCA both exhibit similar toxicological properties, they often collected and reported together as total THC.

LCS Laboratory offers air sampling procedure for evaluation of THC concentration in air of green houses, laboratories, and packaging stations. Your sampling kit includes air sampling pumps, and sampling media. The samples are collected on 37 mm filter at 1-2 L min for a total volume of up to 500 L of air. The samples are analysed by High Performance Liquid Chromatography and  reported by our laboratory with sensitivity of 1 ug/sample.  The test is recommended for assessment of occupational exposure limits of workers who are involved in harvest, drying and packaging of medical marijuana.

LCS Laboratory offers other tests for assessment of occupational exposure in medical marijuana production. Please email us to request additional information.
