“…It is not the pharmacological effect of the drug alone that enhances social behavior, but rather the interaction with social stimuli. Psychostimulant drugs, such as cocaine, amphetamine, methylphenidate, methamphetamine, and MDMA, are also used in a social context as a "social lubrication" (Britt & McCance-Katz, 2005;Ramo, Grov, Delucchi, Kelly, & Parsons, 2011) and appear effective at low-medium dose ranges (Morgan, Noronha, Muetzelfeldt, Fielding, & Curran, 2013). In addition to arousal and increased attention, people become more disinhibited and self-confident, while fatigue is suppressed, facilitating prolonged social interaction (Fischman & Schuster, 1980).…”
