Do not lie about the potency of your prerolls. At least, not in California because you’ll get sued if your joints are not as strong as your label says. The California Department of Cannabis Control requires companies to label cannabis products with their THC content, expressed as either a percentage or in milligrams. And the THC content on the label must be within 10% of the actual THC content. There are customers who are very particular about the high they need and will take action if they believe they are being shortchanged.
