Once drug addicts end up admitted into a heroin clinic they receive twice-daily prescription doses of state-funded heroin, the Fyens Stiftstidende reported.
Mette Guul, head of Reden Odense, a YWCA center for abused women and prostitutes in Aarhus, said many don't know how to handle their newly found free time, the Fyens Stiftstidende said.
"The women say they are lonely, bored and do not know what to do now that they do not have to chase the drugs anymore," Guul told the newspaper.
Guul said her facility offers several kinds of cooking classes, Internet lessons, bicycling, museum visits and crocheting which are popular with the women seeking treatment, the Copenhagen Post reported.
Staff at the Reden heroin clinic said they also noticed more women showed up to sew or knit now that their time is not spent looking for their next fix.
"They say they are lonely, bored and do not know what to do now that they do not have to chase the drugs anymore," Guul told Fyens Stiftstidende.
