House Republicans advanced a budget plan that would prevent legal sales of marijuana in the District until at least 2017. Advocates for legalization, however, called it a victory. What the Republican budget does not do yet is roll back Initiative 71, the voter-approved measure from November that legalized pot for recreational use in the nation’s capital. Since early this year, D.C. residents have been allowed to possess, grow and, in the privacy of their own homes, smoke marijuana.
