Wrong. The masses are sheep for one. Additionally, Tobacco is legal, but not to grow at home. Tobacco isn't that hard to harvest. You can put it in a garden, but do people? NO. Alcohol is essentially easy to still(yet illegal to do so) yet no one does. If the Gov oks it, it will be controlled the same way. If it was legalized, big grow ops wuould make the product cheaper and less of a hassle then doing it at home. People will buy and pay the tax.
