California has entered a whole new era and the days of cannabis prohibition are fading into the past. As of January 1st, 2018, California became the most populous U.S. state to legalize recreational cannabis use. The Golden State is not just transitioning from a medical marijuana-only state to a fully rec-legal state, however, it is also transitioning from a largely unregulated market to a tightly controlled one. This means that there are numerous laws, rules, and regulations governing exactly when, where, and how you can use pot. For Californians who are used to the “wild west” days of the unregulated medical marijuana market, or for tourists looking to legally purchase marijuana for the first time ever, the list of rules and regulations can be confusing. But there's no need to spend hours Googling the guidelines – MERRY JANE has prepared a concise list of do's and don'ts that will you have you sparking up on the right side of the law in no time.
