The levels of THC-A, THC and THCtot measured in n = 206 Cannabis Cautioning seizures from NSW.Levels of cannabinoids are expressed as % of total weight of sample (w/w%). THCtot levels are obtained from adding the amount of free THC seen in the cannabis to the amount found in the non-psychoactive from of THC-A while adjusting for the differing molecular weight of the cannabinoid and carboxylic conjugative components of each cannabinoid (THCtot = THC+THC-A*(314.46/358.47)).
