WASHINGTON — It's easy for Congress to meddle with the District of Columbia's decision to legalize recreational use of marijuana, but taking on the states is a different matter.
A catch-all spending bill Congress passed last week would prevent the District from using federal and local money to implement any law or regulation that repeals or reduces marijuana-related penalties. The action is in direct response to a voter initiative passed last month that allows possession of up to 2 ounces of pot or up to three mature plants for personal use.
The Constitution gives Congress the power to review and possibly reject all legislation approved by the District's elected officials or its citizens.
Congress has less leverage with the states, and thwarting efforts supported by a plurality of voters back home could prove risky at election time.
"That's sort of asking for a head-on collision with states' rights," said Philip Wallach of the Brookings Institution, a Washington-based think tank.
Wallach said the most ready tool at Congress' disposal in persuading states to keep marijuana illegal would be to withhold money for certain programs if state marijuana initiatives conflict with federal law. That's something Rep. Trent Franks, R-Ariz., chairman of a House panel on the Constitution and civil justice, says he's prepared to support.
Franks said the marijuana legalization movement endangers youth. Many other Republican lawmakers don't seem ready to take such concrete steps, including Sens. Charles Grassley of Iowa and Ron Johnson of Wisconsin, the likely chairmen of committees that could deal with marijuana laws in the next Congress.
Grassley wasn't prepared to say what issues the Judiciary Committee will focus on; Johnson said he'd like a hearing by the Homeland Security and Governmental Affairs Committee on how marijuana legalization is working but that's as far as he would commit.
