Understanding the legality of cannabis can be tricky. While cannabis remains federally illegal, its legality differs on a state to state level. While some states recognize the federal illegality of cannabis, other states have adopted medical marijuana and recreational marijuana.
For an in depth list of the laws and regulations for your state, we recommend checking out the NORML website, their mission is as follows:
NORML's mission is to move public opinion sufficiently to legalize the responsible use of marijuana by adults, and to serve as an advocate for consumers to assure they have access to high quality marijuana that is safe, convenient and affordable.
