The Origins of MAUCRSA: A Timeline

California’s marijuana laws are laid out in the Medicinal and Adult-Use Cannabis Regulatory and Safety Act (MAUCRSA). This is how California got there.

Why are Local Jurisdictions Suing the State of California Over Cannabis Delivery Services?

According to Proposition 64 (the adult-use cannabis law voters approved in 2016), licensed retailers are authorized to deliver cannabis state-wide. However, Prop. 64 also gives local jurisdictions the power to ban commercial cannabis activity within their borders. This has created some controversy when it comes to cannabis delivery services. 

Continue Reading Below

Jurisdictions that have banned commercial cannabis argue that they should also be able to ban cannabis delivery as well. However, the Bureau of Cannabis Control has made rules enabling cannabis businesses to deliver product to local jurisdictions with commercial cannabis bans as long as they are in compliance with state and their home-jurisdiction’s cannabis rules.

In response to this conflict, the following 24 cities and 1 county are suing the state of California in order to uphold their cannabis delivery bans: 

  • Agoura Hills
  • Angels Camp
  • Arcadia
  • Atwater
  • Beverly Hills
  • Ceres
  • Clovis
  • Covina
  • Dixon
  • Downey
  • McFarland
  • Newman
  • Oakdale
  • Palmdale
  • Patterson
  • Riverbank
  • Riverside
  • San Pablo
  • Sonora
  • Tehachapi
  • Temecula
  • Tracy
  • Turlock
  • Vacaville
  • Santa Cruz County 

If local jurisdictions are permitted to ban the delivery of cannabis within their borders, a significant portion of California residents would have to drive to another city to obtain cannabis.

Driving Under the Influence 

It is illegal to drive under the influence of marijuana. Although there is no single method for law enforcement to charge a person for driving under the influence of cannabis, police officers can make that call based on the following:

  • marijuana odor
  • statements 
  • demeanor 
  • field sobriety test performance 
  • presence of cannabis in your vehicle 

Penalties for a first-time cannabis DUI conviction include:
