Since testing began in July, nearly 20 percent of marijuana products in California have failed potency and purity tests, according to AP News.
The testing has found unacceptable levels of pesticides, solvents, and bacteria, including E. coli and salmonella, according to data from the California Bureau of Cannabis Control. Some of the tests found incorrectly labeled products with the wrong potency.
In the first two months of testing, almost 2,000 of the 11,000 samples failed. The testing has led to about one-third of cannabis-infused cookies, candies and tinctures being blocked from the shelves of dispensaries.
About 90 percent of the buds that were tested were sent on to dispensaries, according to US News and World Report. The rejection rate was higher for concentrates – with 20 percent of oils and waxes not making the cut.
