Increased marijuana legalization is a wonderful thing. But it has also caused some confusion. Weed is not yet legal on a federal level. As a result, weed laws change from state to state and city to city. It’s difficult to know what applies in your location.

It allowed non-retail medical uses (such as distribution, processing, manufacturing, transportation, research, development, and testing) in an area of the city known as the “Green Zone”.
- Measure Q: The Costa Mesa Retail Cannabis Tax and Regulation Measure, or Measure Q, was approved by voters in the 2020 election. It allowed the city to create rules that set guidelines for cannabis use, dispensaries, and delivery.
Formal reviews and public hearings have been conducted since 2022 to determine which businesses would be licensed.

Federal Law Can Apply to Using Weed in Costa Mesa
Using weed in Costa Mesa and other parts of California is legal. But marijuana is still illegal under federal law. The Controlled Substance Act (CSA) still sees marijuana as a Schedule 1 drug meaning it has little medical benefits and a high addiction risk.
Recent laws have been enacted to protect people who cultivate, possess, or transport weed while complying with state laws. However, federal prosecutors may still arrest people for possession or cultivation even if they are following local laws. Arrests will typically occur if the individual is linked to large-scale traffickers and organized crime units.
