Cannabis Test Panels

What does Cannabis Potency %weight mean?


Usually potency is reported as a %weight of the sample, especially for raw plant materials, since an accurate volume cannot be determined. For example, a gram of raw plant material contains a certain %weight of cannabinoids. Thus, if the %weight for THC is 5 %weight, it means that any weighed portion in grams of the sample should contain 5% THC in grams. If 10 grams of sample is weighed 5 %weight would translate to 0.5 g of THC. For a more detailed information leaflet 1.) Navigate to the home page 2.) Click on the downloads menu button 3.) Look for the Cannabis Potency Icon 4.) Click the download info button




What does Cannabis Potency mg/mL mean?


To obtain a different unit such as mg/mL compared to %weight, the %weight of the sample as well as the density needs to be known. To translate %weight to mg/mL a certain volume of liquid sample needs to be weighed in order to determine the sample density. From this density the mg/mL of cannabinoids can be calculated using the %weight unit. NAFS offers Potency mg/mL content as a test panel where %weight as well as density is determined. For a more detailed information leaflet 1.) Navigate to the home page 2.) Click on the downloads menu button 3.) Look for the Cannabis Potency Icon 4.) Click the download info button
