Another highlight from Mother Jones interview noted earlier, Loughner quit smoking pot a few years ago, according to his friend:

In October 2008, [Bryce] Tierney was living in Phoenix, and Loughner came to visit. They went to see a Mars Volta concert with friends, and Tierney was surprised when Loughner said he had quit partying "completely." Loughner, according to Tierney, said, "I'm going to lead a more healthy lifestyle, not smoke cigarettes or pot anymore, and I'm going to start working out." Tierney was happy for his friend: "I said, 'Dude, that's awesome.' And the next time I saw him he was 10 pounds lighter." Tierney never saw Loughner smoke marijuana again, and he was surprised at media reports that Loughner had been rejected from the military in 2009 for failing a drug test: "He was clean, clean. I saw him after that continuously. He would not do it."
