So which mind-altering substance are you going to use this time while claiming you haven't relapsed because it's not illegal to purchase?
Idk the story here but that was not in good taste, mature, or wise.
It's pretty much exactly what it sounds like. He's been "in rehab" multiple times, always says the exact same crap about how he's turning his life around and he's totally a different person, and then promptly goes back to being a druggie. He said he was "clean" a while ago while tripping on cough syrup regularly nearly every day. He claimed he was still clean because it didn't count as a drug since you could buy it off the shelf.
He's a lost cause and doesn't deserve sympathy or support because he's proven at least a dozen times now that he's not actually interested in being better.
