Dave Dunkel, owner of Sees-the-Day, center, shares a cigarette break with, from left, Zachary Moser, 21, of Montgomery County, Pa.; Nathan Embry, 27, of Lancaster; and Roman Fissel, 22, of Manchester Township, all of whom live in a Sees-the-Day recovery house on Linden Avenue in York, Pa., on Wednesday, Feb. 10, 2016. Many recovering addicts are smokers, as cigarettes and nicotine replace the addictions from which they are recovering. York is home to a figuratively underground community of about 80 recovery homes that house drug and alcohol addicts. Many recovering addicts are sent to the houses by York County's probation department as an alternative to jail or homelessness, while other addicts come to York on referral from other treatment facilities or of their own volition. The houses, which are not designed as treatment programs and which can each house 5-12 recovering addicts, are not subject to state or county regulations . While owners of many recovery houses in York refused comment, other owners said their homes are structured to provide a system of support and accountability by requiring residents to attend 12-step meetings and gain employment, with the ultimate goal of graduating sober after a residency of about six months.
