What was the first state to decriminalize pot?
The first state to decriminalize pot was Oregon, who did so in 1973. Possession of one ounce or less was classified as an infraction carrying a $1000 maximum fine with no jail time. A 1986 ballot measure sought to take matters even further and legalize marijuana outright, but voters rejected the measure by a decisive three-to-one margin. In 1997, the Oregon state legislature passed a new bill, which made possession of less than one ounce of pot a Class A misdemeanor.
