Fireworks Illegal?

Should fireworks be illegal in California? As it stands, they currently are. Yet in other states they are allowed. My stance on this is the creation of an illegal item, adds to the desire to use them. If a state wants to prevent injuries and fires, banning fireworks would only increase the sells of unsafe ones. Whereas, if they remained legal, a government would be able to regulate the safety of the items being sold. In the process creating less damage and fewer injuries.
