No. 19: New Hampshire Legalizes Medical Marijuana That makes all of New England By John Johnson, Newser Staff | Suggested by pg13 Posted Jul 23, 2013 6:39 PM CDT 98 comments Comments Medical marijuana is now legal in all of New Hampshire. (AP Photo/Ed Andrieski, File) (Newser) – Smoking pot is now legal in all of New England—provided you have a doctor's permission. New Hampshire today became the last state in the region to approve, as Gov. Maggie Hassan made it official, reports the Union Leader. It joins 18 other states.

And first up with the "Live Free or High" headline is the New York Daily News.
