Residential, care and supported living premises will ban smoking from this Friday.
The move will make all Department of Health and Social Care and Manx Care sites smoke free.
It marks the final stage of introducing the smoke free policy and means it will no longer be permitted anywhere on Department or Manx Care grounds.
The policy is a key milestone in the ambition to reduce the number of people smoking to under 5% of our Island population.
From April 1, vaping will only be permitted in outdoor areas away from doorways, open windows and anywhere that may cause nuisance to others.
This will apply to all staff, visitors, patients and residents at all sites.
