Associations between stopping prescriptions for opioids, length of opioid treatment, and overdose or suicide deaths in US veterans: observational evaluation

Study (n=1,394,102) found patients were at greater risk of death from overdose or suicide after stopping opioid treatment, with increase in risk the longer patients had been treated before stopping [HR 1.67 (≤30 days), 2.80 (31-90 days), 3.95 (91-400 days), and 6.77 (>400 days)].
