Mortality for methadone vs. buprenorphine

I recently stumbled on this article about methadone treatment in Oregon. I’d say the article is positive about maintenance drugs, but these sentences lept out at me.

Opiate addicts who entered methadone programs were nearly five times more likely to die from drug overdoses within the first four weeks of treatment than those who entered buprenorphine programs, according to a study published online in The Lancet in September. Researchers with the National Drug and Alcohol Research Centre in Australia retroactively followed about 32,000 opiate addicts after entering therapy programs. Those taking methadone were also twice as likely to die from any cause.

The Lancet article is paywalled.
