The Town of Islip, centrally located on Long Island's South Shore in Suffolk County, is home to over 335,000 residents across diverse communities including Central Islip, East Islip, Bay Shore, Brentwood, Hauppauge, Ronkonkoma, Holbrook, and Sayville.

Substance Use in Town of Islip: Local Context

  • • Brentwood, the largest hamlet in the Town of Islip, generates the highest volume of OASAS treatment admissions of any single community in Suffolk County.
  • • Suffolk County alcohol treatment admissions totaled 4,100+ in 2023, with the Islip corridor (Bay Shore, Brentwood, Central Islip) representing the highest geographic concentration (OASAS).
  • • Two major hospital systems — Southside Hospital (Bay Shore) and Good Samaritan University Hospital (West Islip) — serve the majority of Islip Town's substance-related emergency cases.
  • • Polysubstance use (involving two or more substances) accounts for 68% of treatment admissions in central Suffolk County communities (OASAS 2023).

The Town of Islip stretches across central Suffolk County from Great South Bay's barrier islands to the inland hamlets of Deer Park and Brentwood, encompassing one of the most demographically diverse corridors on Long Island. The Bay Shore Fire Island Ferry terminal and LIRR Babylon Branch connectivity make this a well-served transit corridor, though treatment access remains uneven between waterfront communities and inland hamlets.

Nearby communities with dedicated resources include Bay Shore, Brentwood, Central Islip, West Islip, and Islip Terrace.
