It was first synthesiSed in the 1930s and has been used in a variety of industrial and commercial applications, including as a solvent for cleaning products, as a paint stripper, and as a component in some plastic and fibRE production processes. In recent years, however, it has become more well-known as a recreational drug due to its ability to produce feelings of euphoria, relaxation, and sedation.

However, when consumed in larger doses, it can cause more serious effects, including:

  1. Impaired coordination and balance
  2. Nausea and vomiting
