A Harvard Medical School study found that recovery housing residents were twice as likely to remain abstinent (65% vs. 31%). Additionally, they had an incarceration rate of a third of what it was for those not in recovery housing (3% vs. 9%). The findings suggest that incentives matter, not only for staying off drugs but also for staying out of jail. Getting support from the right community, combined with incentives to stay on track, increases likelihood of success.
