The New Hampshire House of Representatives recently became the first state legislative house to pass marijuana legalization. Legalization measures adopted in Colorado and Washington in 2012 passed by referendum. As the above-linked Concord Monitor article notes, the law faces tough sledding in the state senate, and could well be vetoed by New Hampshire’s Democratic Governor Maggie Hassan. Nonetheless, it is an incremental step forward for the cause of legalization, which has been gaining ground in both public and elite opinion in recent years.
