Former classmate Caitie Parker remembers Loughner as a "pot head". Loughner has a history of drug use, having been arrested in September 2007 for possession of marijuana and drug paraphernalia. "I haven't seen him in person since '07," Parker recalled in early 2011. "I'm looking back at this [as] a 14–19-year-old...who knows if any of us knew what for sure we were yet."
