With Season 6 set in 1968, it's no surprise Mad Men featured plenty of pot smoking. In one episode ("A Tale of Two Cities"), Don (Jon Hamm, right) got high on hash at a party in Los Angeles as the Democratic Convention riots played out on television from Chicago. Don had another affair, jeopardizing his relationship with his stoner wife, Megan (Jessica Pare). Season 7 on AMC will be Mad Men's last, wrapping up in 1969.
