Why marijuana laws should be left to the states

As officials in Washington and Colorado proceed with plans to sell state-regulated marijuana, they're nervously looking over their shoulders at Attorney General Eric Holder, wondering how the Justice Department is going to handle a seeming conflict between federal law (pot is illegal) and their state laws (pot is legal).

An op-ed in the Los Angeles Times does a good job of explaining why there really isn't much of a conflict between the states and the feds here. The authors should know what they're talking about. Erwin Chemerinsky is dean of the UC Irvine School of Law. Allen Hopper is criminal justice and drug policy director of the ACLU of California.

Here's some excerpts from "On Pot Laws, Respect the States" by Chemerinsky and Hopper.

It may be surprising, but no state is required to have a law making possession of marijuana, or any drug, a crime. Therefore, any state can legalize some or all marijuana possession if it chooses. The federal government, if it chooses, can enforce the federal law against its possession and use, but it is up to each state to decide what to criminally prohibit, based on the 10th Amendment.

…There is not a conflict when one level of government prohibits something but another level of government does not. An easy illustration is that murder is a crime in every state, but, except for very specific circumstances, it is not a federal crime. No one would say that there is a conflict. Likewise, a state can decide that certain conduct does not violate state law even if it offends federal law. It is then for the federal government to decide how, if at all, it wants to enforce the federal law.

…Several other states, including California, have laws making possession of up to an ounce of marijuana an infraction punishable by a fine, even though under federal law, it's a misdemeanor punishable by up to one year in federal prison. Similarly, 17 states and Washington, D.C., have laws that allow possession of marijuana for medical purposes; there is no such federal exception. Although the federal government can enforce the stricter U.S. law in states that have decriminalized possession or have medical marijuana laws, it has never acted to have those state laws invalidated based on the preemption doctrine.

Simply put, no state has to have a law prohibiting marijuana, even though federal law does. And if a state does have such a ban but wants to repeal it in whole or in part, such as for possession for medical reasons or for small amounts, it may do so.

…Beyond the legal arguments, there are policy reasons for the federal government to not interfere with the Colorado and Washington laws. An important feature of federalism is that states are empowered to serve as laboratories for experimentation with social policies. As the nation embarks on perhaps the most significant public debate about drug policy since President Nixon declared the war on drugs, Washington and Colorado's experiment should be allowed to go forward. The country can then assess whether it succeeded or failed.
