The use of tobacco was so widespread in America that it was once thought to be impossible to curb it. And yet tobacco use is now in serious decline and it is widely consider to be uncool to smoke. Was this accomplished by making smoking illegal? Of course not. Making smoking illegal would have made it only more desirable? A combination of targeted taxation, a persistent ad campaign, and cultural taboos defeated the very addictive habit of smoking and made it less and less prevelant. Marijuana foes could only hope for such success against the drug they oppose.
Mr Brown is a dinosaur. Everyday there are fewer and fewer people who seriously believe making marijuana illegal is a viable solution to marijuana addiction and the problem it creates for society. For those who want to see less marijuana usage, follow the example of tobacco.
