Edible marijuana products are readily available in over 30 of the United States due to legalized medical and recreational marijuana laws. Popular edibles include cookies, cupcakes and gummy bears. Even though there are a plethora of these products available, only 17 percent of them have accurate ingredient and marijuana dosage information on them. This is concerning because it is always safe to know the dosage of cannabis in the products.

Researchers from the American Chemical Society have created new technique to test the amount of cannabis and other ingredients in these products. It is currently very hard to do so because the testing technique available now, which is the High Performance Liquid Chromatograph (HPLC) test, does not test edibles well due to their starchy and fat contents. These contents ruin the equipment used in these tests and lead to inaccurate and unreliable results.

The new technique would infuse the edible marijuana food samples into a cyro-mill dry ice or liquid nitrogen and create a homogenous sample. This would allow scientists to inject the liquid into the HPLC machines without ruining the equipment. This new technique would measure the compounds in different edibles, which would lead to more accurate ingredient and dosage labels.
