us-legal-status-cannabis-20141122Smoking, growing, buying, selling or merely possessing cannabis is a criminal offence, according to America's federal government. Ask the states, however, and you will get almost 50 different answers. In 13 of them possession of the drug has been decriminalised, meaning that tokers face only minor penalties if caught. In 23 it has been legalised for medical use. And in four—including, following ballot initiatives earlier this month, Alaska and Oregon—cannabis has been legalised outright. In all only 22 states, fewer than half the total, continue to treat the drug as criminal contraband under all circumstances.
