LYNN – A Brookline-based addiction treatment center has abandoned its search for a Lynn site with the real estate agent representing New Horizons saying the center is “completely in park” on all local plans for a location.?I don?t know what they are going to do now,” said Christopher Bibby.Bibby earlier this week said he had been representing New Horizons for four months in its search for a Lynn location. He said the search was part of New Horizons? efforts to site medical offices in Massachusetts cities.In a Friday interview, Bibby said he did not know New Horizons? plans for its treatment site search and a New Horizons representative who declined to be identified on Friday said the treatment center abandoned its search for a downtown Lynn location.?We are backing out,” the representative said.A Central Square area location was one of what Bibby earlier this week called “a handful” of Lynn locations New Horizons considered for sites. He said the treatment center wanted a 2,500 to 4,000 square foot space where doctors could counsel addicts seeking to stay heroin-free and prescribe suboxone.The treatment center?s search for a Lynn site sparked objections from city Economic Development and Industrial Corporation Director James Cowdell and Police Chief Kevin Coppinger.New Horizons? website distinguishes suboxone from methadone as an opiate addiction treatment option, describing suboxone as “…the first opioid medication approved for the treatment of opioid dependence in a private office setting.”Bibby said suboxone “keeps you straight.”?You have to be off drugs to be in this program,” Bibby said earlier this week.Coppinger raised concerns about New Horizons opening in Lynn. He said any plan to locate a treatment center in the city has “an impact on valuable police resources.”?It?s very difficult to kick the habit. A lot of people relapse and we get the calls,” Coppinger said.
