"Street names for some phenethylamines include ‘Europa’ for 2C-E; ‘4-FMP’, ‘para-fluoroamphetamine’, ‘RDJ’ for 4-FA; and ‘4-MMA’, ‘Methyl-MA’ for PMMA. Phenethylamines are usually available in form of pills, but FLY compounds are commonly sold in powder form, while oral doses (on a slip of blotter paper) are usually available for ‘D substances’. Ingestion is the most common route of administration of phenethylamines."
