When it comes to cannabis products, the amount of THC or CBD available for consumption is not always as simple as reading the “total THC number” on the label. There is no official industry standard for calculating the total THC of a cannabis product, and different producers and testing centers calculate it in different ways. HLPC (High-Performance Liquid Chromatography) is an effective method for evaluating the level of THC in oil. If the oil has a thick consistency, it may be necessary to reduce the viscosity with the addition of isopropyl alcohol before solvent extraction can be used and the analysis performed.
Method 1, which only adds up the percentages of THCA and THC, is too simplistic and greatly overestimates the THC content. A more accurate estimate of the final levels of THC can be obtained by taking into account the efficiency of the conversion of THCA to THC, which will depend on the time the flower is exposed to heat, the exact heating temperature and the device used. By knowing their THC content, you can weigh your flowers and calculate the exact amount of THC in each dose of oil or delicious brownie. A microdose of ¼ teaspoon, 13.76 ÷ 4 %3D 3.44 mg of THC.
That gram of herb with 100 mg of THC multiplied by 28 (one ounce of herb equals 28 g), gives a total of 2800 mg of THC for one time or marijuana, or 100 mg for each gram of herb. The molecule is converted to THC when exposed to the heat of a pipe, vaporizer or oven in a process called decarboxylation that expels the carboxyl group, leaving THC behind.
