[PAR] [TLE] Metaproscaline [SEP] Metaproscaline, or 3,4-dimethoxy-5-propoxyphenethylamine, is a lesser-known psychedelic drug.  It is an analog of proscaline.  Metaproscaline was first synthesized by Alexander Shulgin.  In his book "PiHKAL (Phenethylamines i Have Known And Loved)", the dosage and the duration are unknown.  Metaproscaline produces few to no effects.  Very little data exists about the pharmacological properties, metabolism, and toxicity of metaproscaline. [PAR] [TLE] Propane [SEP] Propane ( ) is a three-carbon alkane with the molecular formula CH.  It is a gas at standard temperature and pressure, but compressible to a transportable liquid.  A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel for barbecue grills. Propane is one of a group of liquefied petroleum gases (LP gases).  The others include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof.
