If you are looking to set up a cannabis business, then it is important for you to obtain a medical cannabis business license. The type of documentation and licensing that your business will require may depend on where you intend to set up your business as well as the type of business operation you will be conducting. 
For example, you may be required to obtain a different permit for cannabis cultivation and a different one to run a cannabis dispensary.
Different states also have different approaches to how they regulate cannabis business. In the state of California, selling cannabis for both medical and recreational use is legal. But, it is important that the seller has obtained a local license as well as a state license. 
The state also has three licensing authorities which issue different types of licenses such as cultivator, testing lab, retailer, etc.
Regardless of which state you really want to operate, you will see that there are restrictions put in place on how many cultivator and dispensary licenses will be issued. This is done so that authorities can regulate the industry and prevent illegal activity from taking place. When obtaining a medical cannabis business license, you may also have to come across certain barriers such as strict regulations, stringent management and financial reporting requirements as well as the high costs associated with starting a business.
