California now has the most rigorous testing requirements: Every cannabis product sold in a licensed dispensary is tested for 66 types of pesticides, heavy metals, microbial pathogens and potency. A more effective way to prevent people from using marijuana vape pens that could kill them or make them sick would be to legalize weed so that consumers could have the option to buy regulated, lab-tested products. The public health benefit of legalizing and regulating marijuana is not hypothetical — it’s already happened in states that have done it. Back in 2017, before California’s testing requirements went into effect, around 70% of clients that submitted their product to cannabis-testing lab Cannasafe failed to meet standards the lab was using at the time, according to Antonio Frazier, the lab’s vice president of operations. These days, only 3-6% of Cannasafe’s clients fail to meet the state’s testing regulations. that’s because failing these testing requirements is a huge pain for cannabis companies. Products have to be quarantined. The manufacturer can either destroy the entire batch or submit a “corrective action plan” to the California Department of Public Health, which decides whether or not to approve the plan. “Our fail rate was much higher when no one was required to do it the right way,” Frazier said. “Without regulation, people aren’t going to do what’s right. This has been true in almost all industries.” Legalization and regulation isn’t a perfect solution. There is still a thriving illicit market in California for consumers who don’t want to pay dispensary prices or who live far away from licensed stores.
