I do not believe the government should use taxes as a way of changing behavior. Sin taxes on alcohol and tobacco are obvious examples of how the tax code is used to discourage certain activities. Unfortunately, many have come to accept this method of meddling in how we live. But to be consistent, those who accept it should then also support any tax on behavior that the majority (or those more powerful than us) disfavor. Soda taxes, juice taxes, and french fry taxes are fully consistent with this model. Continuing this approach, why not tax lack-of-exercise, too vigorous exercise, and any other behavior that could do one harm? After all, the argument goes, we the taxpayers are paying more for government-run health care these days, shouldn't responsible government be encouraged to dictate behavior? Taxing any disfavored behavior takes us down a slippery slope leading to government intervention into every decision we make. Such a scheme could never be fair and effective.
Another problem with this type of tax policy is that it is highly subject to be misapplied because of a distorted understanding of the risk being taxed. As we'll see in a moment, the taxes on different types of tobacco are a prime example. Until we overturn our heavy-handed behavior-modifying system, we should work to ensure that the tax on any disfavored behavior is tied to the actual risk society is trying to reduce.
But most tobacco taxes fail to differentiate between the different risks of different tobacco products. Cigarettes and smokeless tobacco, or snus, present very different risks. Burning and inhaling tobacco is what makes it so extremely dangerous. The use of smokeless tobacco, while not 100% safe, comes nowhere near the risk. That is because it is not burned and not inhaled. Therefore, it doesn't come with the major risks of heart disease, lung cancer, and systemic illnesses caused by smoking.
Yet cigarettes and snus are taxed at about the same rate, even though their risks are vastly different. It is like taxing a 64 ounce serving of soda about the same as a 12 ounces. This is where Indiana caught up with the science and changed their tobacco tax rate. They encoded in law their finding that "the tax rate on smokeless tobacco should reflect the relative risk between such products and cigarettes."
This marks the first time any state has codified such a rational rationale.
