If quitting smoking was easy, no one would smoke. If loosing weight was easy, everyone would be thin. If quiting drinking was easy, there would be no Alcoholics Anonymous. You never know what another person's level of struggle is looking from the outside. I have a video interview from Japan, I think late 1996 or early 1997, where Jon was smoking and he vowed that was his last pack. He's tried to quit. Tico quit for a while and started again. When everyone in the band is smoking around him, it's got to make it that much harder for Jon to "just say no."
