There is so much controversy over the legalization of marijuana, where it's legal and what the parameters are. Some states have voted to make the recreational use of weed legal. This would mean that at any given time you can possess a certain amount of the substance on your person and then a given amount at home. Other states have said that medical marijuana is legal but recreational use still illegal. Then the rest of the states have no laws legalizing the plant.

Here is the list of states in each category:
