ANNAPOLIS, Md. (WNEW/AP) — Maryland Gov. Larry Hogan has vetoed a bill that would have decriminalized smoking marijuana in public, as well as the possession of drug paraphernalia.

In April 2014, state lawmakers adopted a bill decriminalizing the possession of less than 10 grams of marijuana, and then-Gov. Martin O’Malley signed the bill into law.

Adults caught holding small amounts of the drug can get a fine with no jail time, court appearances or criminal record. But possession of the drug paraphernalia used to smoke marijuana, such as a bong or a pipe, is still considered a crime, as is actually smoking the drug in public areas.

In a statement explaining the veto, Hogan cites “legal uncertainties including the elimination of criminal sanctions for the use of marijuana while operating a motor vehicle or in a public setting.”

The Marijuana Policy Coalition of Maryland calls this reasoning “inaccurate” and is attempting to override the veto.
