"Schifano et al. (2010) analysed the government data on recreational stimulant deaths in the UK between 1997 and 2007. Over this period, there were 832 deaths related to amphetamine or methamphetamine and 605 deaths related to Ecstasy/MDMA. Many were related to multiple-drug ingestion or ‘polydrug’ use. However, in the analysis of ‘mono-intoxication’ fatalities, Schifano et al. (2010) found that deaths following Ecstasy use were significantly more represented than deaths following amphetamine/methamphetamine use (p < 0.007)."
