According to Gould, (2010). different studies have shown the negative effects of drug use on working memory: Morphine has been shown to impair working memory (Friswell et al.,2008); polydrug users who preferred cocaine or heroin, continued to have cognitive impairments, including working memory, up to five months into abstinence (VerdejoGarcía, and Pérez-García, 2007); methylenedioxymethamphetamine (MDMA, ecstasy) caused working memory impairment even two and a half years after cessation of use (Thomasius et al., 2006); also in abstinence, cessation of nicotine causes deficits in working memory (Kenney and Gould, 2008); as does cessation of alcohol (Moriyama et al., 2006). Nicotine is linked to poor cognitive functioning in middle age men and women, and during abstinence, the severity of decreases in cognitive performance predicts relapse (Patterson et al., 2010; Rukstalis et al., 2005, as cited by Gould, 2010). Ecstasy increases the dopamine and serotonin levels, and stimulates norepinephrine production, and through continued use, can stunt natural production of these neurotransmitters.
