I mean really. He's a habitual liar. How many decade long heroin users never end up using a needle? How long does it take to put a key in a bag and snort in the bathroom, yet he never can get his fat ass back after the commercial break in the chair 10 yards away half the time during the show. When was the last time you saw Artie wear a short sleeve shirt? And his fiance just so happens to have free access to clean needles. I call bullshit. Shit, even philip seymor hoffman being a raging addict was able to actually go to this job. Yet Artie can't. That fat fuck is/was on the needle. I don't believe for a second that he just snorted and never shot up. I guess we'll have to wait for the next book/coroner report.
