Prohibition has rarely worked unless the item could be tied to imminent danger and even then excused. Blowfish anybody? There is a huge body of literature that looks at the use of behavior/puritan law systems as a means of controlling subject populations. The fact that prohibition is enacted is more important than the items that are prohibited. (e.g) highly punitive drunk driving laws, restricting the driving age, creating a population of convicts has done nothing to stop drunk driving deaths in America. The numbers fluctuate more based on the economy than enactment of punitive laws.
