Kava, a plant known in the South Pacific for its soothing qualities, caught on with New Age spiritualists many years ago, as did kratom, a stimulant native to Southeast Asia. Recently, both plants have found a new consumer base. The legal drugs are experiencing a boom among fitness junkies and young urban professionals. Enter Lacuna Kava Bar, a relatively new downtown drinking establishment where hippie-plant evangelists congregate day and night. Stop by for an afternoon study session propelled by a cool kratom prickly pear lemonade. Or, skip the bars on a Friday evening and enjoy a hangover-free "kava colada."
