Cannabis and CBD are legal in Denver for both medical and non-medical use. However, the city still enforces the Marijuana Code, which requires all cannabis providers to be licensed and follow strict advertising limits.
That means you can’t make any claims of curing ailments, broadcast any mass media ads, or target consumers under 21 years old. Working with a specialized cannabis marketing agency in Denver is an easy way to ensure your content meets these guidelines.
Here are the 10 top cannabis and CBD marketing agencies in Denver, Colorado.
