Since the state's requirements are still unknown, testing methods and equipment may vary from this response. However, the most common forms of testing cannabis will be explained.
The first is Gas Chromatography (GC). GC is widely used in the medical industry for detection of element types and amounts in compounds and solutions. GC uses heat to vaporize the marijuana which is first broken down in a solvent. This vapor is analyzed by a chromatograph. This is most likely to be the avenue which will be chosen for testing, since almost all cannabis is heated to some extent for use. It is either smoked, or put in edibles which are heated. Chocolate, candy, brownies, etc. all are heating the cannabis during processing. This can and will change the properties of the cannabis during processing. Therefore, using heat in the analysis process would be a good idea in our opinion.
High Performance Liquid Chromatography (HPLC) is also a method of detection. HPLC does not use heat, so some say this is more accurate of what you would purchase right out of the bag. However, not many people use cannabis right out of the bag. We guess you could just sprinkle it on a salad for consumption, but this is a low occurrance. HPLC uses high pressure pumps to pass the cannabis, which is also broken down in a solvent, through the chromatograph for analysis.
Mass Spectronamy is a further in depth analysis tool. It uses a technique which separates elements by molecular weight into ions to identify what is in your cannabis. It can be used in tandem with chromatography to give more details of compositions within the cannabis being tested.
Finally, Microscopy is simply the use of a microscope with human or machine vision to determine the presence of compounds within the test sample. Something sprayed onto the plant material during the growing, harvesting, or processing of the cannabis can usually be detected by this method of testing.
Smokeabud.com LLC believes that a combination of these methods will have to be used to determine the cannabis potency, purity, and quality per guidelines to be determined by state authorities. Some of these methods of test are quite expensive equipment purchases. We will strive to procure the best equipment and methods to protect the consumer.
