Moisture Content Testing
Moisture content is not a required test by most states. However, moisture can be extremely detrimental to the quality of stored cannabis products. Dried cannabis typically has a moisture content of 10-12%. A moisture content above 12% in dried cannabis is prone to fungal growth (mold). As medical users may be immune deficient and are highly vulnerable to the effects of mold, constant monitoring of moisture is needed.
SCIENTIFIC METHODS
The best way to analyze the moisture content of any product is the thermogravimetric method. This process involves placing the sample of cannabis into the sample chamber and taking an initial reading. Then, the moisture balance will heat up until all the moisture has been evaporated out of the sample. A final reading is then taken to determine the percent weight of moisture that was contained in the original sample.
