An experimental study conducted by the BfR shows that humectants such as glycerine or 1,2 propanediol for the most part evaporate during smoking and can thus be absorbed to a significant degree by the smoker. In animal experiments, inhaling high concentrations of glycerine or 1,2 propanediol led to changes to the cell epithelium in the larynx or to irritation of the nasal mucosa. The BfR therefore maintains its recommendation to limit humectant contents in water pipe tobacco to a maximum of five percent. Newer studies on the composition of water pipe smoke show that it contains high quantities of carbon monoxide, benzene, nicotine and tar.
In 1974, Congress passed the Safe Drinking Water Act.

Each Government at the state level has their own Authority and regulations in place for licensing plumbers. They are also responsible for the interpretation, administration and enforcement of the regulations outlined in the NCC. These Authorities are usually established for the sole purpose of regulating plumbing activities in their respective states/territories. However, several state level regulation acts are quite outdated, with some still operating on local policies introduced more than a decade ago. This has led to an increase in plumbing regulatory issues not covered under current policy, and as such, many policies are currently being updated to cover these more modern issues. Plumbing equipment includes devices often behind walls or in utility spaces which are not seen by the general public.
