When a legal synthetic drug called Amped first shipped in October 2011, fans of recreational narcotics went crazy for it. Marketed as “ladybug attractant” and “exuberance powder,” Amped was developed by a trained biochemist, a rarity in the otherwise fly-by-night industry. But by the end of February something had changed. Comments from Amped users started appearing on blogs, claiming that unlike the initial batches of the fine high-octane stimulant powder that “made ladybugs scatter,” recent shipments were the color and texture of soggy piecrust. The stuff smelled like piss. For those willing to snort this congealed paste, however, it still provided a decent high.
