Marijuana testing gives consumers the information necessary to make a buying decision based on the composition and potency of a marijuana product. Yes, cannabis potency is important to many consumers and so accuracy in testing is crucial, especially since so many medical marijuana patients depend on this. Recreational users also depend on cannabis potency since it influences their experience.
There is a wide range of marijuana testing methods that are used in order to assess potency, quality and safety so that consumers can be adequately informed. Each state has its own testing requirements so you have to find out what that is. There are a few procedures, though, that are common to the cannabis industry. Cannabis potency details are helpful in knowing the exact CBD and THC levels in each product or marijuana plant.
CBD and THC Levels
Data related to cannabinoid potency quantifies the cannabinoid levels found in the cannabis products. The CBD and THC potency data is needed by producers. The levels of CBD and THC have to be known by the consumer so they are aware of how much to consume. For instance, there are some cannabis patients that might desire a marijuana strain that has a higher ratio of CBD:THC while recreational users might want the opposite. Terpenes is also another compound that could be tested, even though, it is not a legal requirement. Right now, we are focusing on cannabis potency testing for CBD and THC only.
THC and CBD Measurement
Let’s now look at how CBD and THC levels are measured in the lab. There are several ways that you can measure the concentrations of CBD and THC. HPLC or High Performance Liquid Chromatography method is most commonly used. This method quantifies the chemical mixture into liquid once it is separated. A collected sample of the marijuana flower is combined with ethanol or other solvent. Using a tube and at a high pressure, the solution is pumped. In the tube, you will find material, which attracts some of the molecules found in the sample and this is based on the material’s chemical properties. There is a detector visible at the end of the column. The compounds that are attracted to the material found in the tube tend to move slower, reaching the detector at a later time.
The cannabinoids will continue through the column after the cannabis sample has been injected. The column and cannaboinoids will interact and this will determine the speed at which each cannabinoid will pass through through the tube. The presence of the each kind of cannabinoid will quantify the detector as soon as it is detected. The lab measurement is then listed on the marijuana packaging. Accuracy in cannabis potency testing is of utmost importance to provide consumer information.
Do It Yourself
You can do your own chromatography testing at home, but you have to use a black marker construction paper and a glass of water. Draw a line with your black marker across the edge of the construction paper. Put the strip of paper upright in the glass of water. However, be sure the marker line is positioned a little bit above the water. Let several minutes pass before you notice the water traveling up the paper, separating the marker’s pigment.
According to a certified lab, states don’t have any strict regulations about how chemicals in marijuana are measured. But it is still important to have measurement for the sake of the consumer, especially as it relates to safety and quality.
