The testing has been especially tough on cannabis-infused cookies, candies and tinctures: About one-third have been blocked from store shelves. Company executives say some products are being rejected after landing outside the margin by tiny amounts. The California Cannabis Manufacturers Association, another industry group, is pushing for changes that include allowing companies to challenge lab testing results. From July 1 through Aug. 29, labs tested 10,695 product batches and 1,904 were rejected, a failure rate of about 18 percent. Testing for a small, outdoor marijuana farm can typically run $5,000 to $10,000 in California.
