A strain of marijuana named by the movie, "American Beauty". This particular strain has never been proven to actually exist. Supposedly it was created for medicinal patients by the U.S. government but anyone who knows anything about the U.S. governemnt knows that they don't provide dank weed for their patients. It's all schwag. People who claim to have smoked this stuff lied to you.
"This is G-13, genetically engineered by the U.S. government". "Is that the stuff we smoked last night?" "This is all I ever smoke." "How much?" "Two grand."
