California Environmental Quality Act Office of Planning and Research to develop and recommend new guidelines to analyze greenhouse gas impacts under CEQA. California’s Natural Resources Agency adopted new guidelines on December 31, 2009, requiring lead agencies to analyze greenhouse gas emissions under section 15064.4 during their CEQA review through California. The major category of greenhouse gas emissions resulting from human activities is carbon dioxide. Several other primary gases also include methane, nitrous oxide, sulfur hexafluoride, perfluorocarbons, and hydrofluorocarbons. Greenhouse gas sources resulting from project construction activities are typically generated from transportation of materials to the project site and petrol based equipment used during construction
Recreational use of nitrous oxide Recreational use of nitrous oxide Recreational use of nitrous oxide is the inhalation of nitrous oxide gas for its euphoriant effects. The gas is sometimes called Whippets, Laughing Gas, the Epiphany Drug, or Hippy Crack. In Australia, nitrous oxide bulbs are known as nangs. Nitrous oxide is a dissociative inhalant that can cause analgesia, depersonalisation, derealisation, dizziness, euphoria, and some sound distortion (flanging). In some cases, it may cause slight hallucinations and have a mild aphrodisiac effect. Research has also found that it increases suggestibility and imagination.
