Although we can all agree that marijuana prohibition has failed, there is not full agreement on how exactly to legalize and regulate it. We still have to answer some important questions. Should people be allowed to grow their own marijuana? If so, how much? Should marijuana be sold in stores? What kinds of taxes should there be? Should there be taxes on medical marijuana products? What about extracts and foods? What is the best age limit? Before we can put a legalized system in place, we need to have the answers to these kinds of questions.
