At the beginning of July, the state of California instituted new safety requirements for marijuana products. And it appears cannabis companies are not living up to those requirements.

According to the data, about 20 percent of marijuana products tested by California labs since the beginning of July have failed to meet the state's required safety limits. Edibles especially have caused problems, as about one-third of products have failed to pass the state's tests.

Now some of these failed tests are a simple case of mislabeling, meaning a company labeled a product as having a potency different than what was actually tested. This can be fixed simply by editing the product's label. But there have been a small number of products that contained unacceptable levels of pesticides, solvents and bacteria, including E. coli and salmonella. 

Some people in the cannabis industry believe a lot of the failed tests are due to the state's strict requirements, and argue that their products are subject to undue scrutiny. Others note that lab tests cannot be challenged by cannabis companies, so if the labs made a mistake, there's nothing a marijuana business can do to respond.

However other groups believe that there isn't enough requirements, and think that the state should add new tests to their protocol for different types of mold.

It's probably too early to tell how the lab tests are affecting the bottom-lines of California cannabis companies, but we should know soon enough.
