Weed sold at New Jersey dispensaries from 17 cultivators and manufacturers did not meet state safety standards for things such as mold and accurate labeling, according to a consumer advocacy group that teamed up with a lab to test products.

Cannabis products are tested before they reach store shelves. The consumer advocacy group, Safe Leaf — worked with an accredited testing lab and re-tested weed sold at dispensaries. The results showed that nearly 30% of tested products failed and exceeded limits for harmful microbes. NJ Advance Media has agreed to grant anonymity to the testing lab.

There were also problems when it came to accurate labeling of THC levels, according to the data. The lab tested 25 pre-rolls from 17 different cultivators and manufacturers. Pre-rolls are cannabis blunts rolled ahead of time and sold to the consumer.
