  • Originated from a project started by the late William Rosen in the U.S. in the late 1980s.
  • Rosen demonstrated that a fluid dropped onto the filters of cigarettes could absorb up to 99% of the tar and nicotine.
  • The product was trialed in the Irish corporate sector in 1995 and in the UK in 1998 as The Rosen Programme.
  • Over 100 organizations introduced the program to their employees and achieved much higher success rates than with any other smoking cessation product.
  • In 2013, the UK became the first country to officially endorse “cutting down” as a recommended strategy for smokers who cannot or do not want to quit smoking entirely.
  • The National Institute for Health and Clinical Excellence (NICE) recommended that doctors inform their patients of these alternatives.
  • NicoBloc is available on a National Health Service prescription in the UK as well as over-the-counter.
  • NicoBloc Fluid has been previously available under the names of Accu Drop, Take- Out and The Rosen Fluid.
  • NicoBloc is now available for the first time in the United States through Bloc Enterprises, the exclusive U.S. distributor.
