1x7 pack of Nicorette chewing gum (nicotine), an aid to giving up smoking, by Lundbeck, expires 1984

Nicorette chewing gum was invented in 1967 in Sweden for men on submarines who would otherwise become agitated without the nicotine fix that cigarettes provided. In 1978, Nicorette was introduced to the general public and is now used as an aid to giving up smoking. The chewing gum contains nicotine, the addictive element in cigarettes. A whole range of Nicorette products, including skin patches, nasal sprays and inhalers have been introduced. This packet of 105 pieces of gum was made by Aktiebologet LEO in Sweden.
