“…Indeed, other studies have demonstrated associations between anhedonia and use of other drugs, including cocaine and amphetamine ( Leventhal et al, 2008( Leventhal et al, , 2010, cannabis ( BonnMiller, Zvolensky, Marshall, & Bernstein, 2007 ;Dorard, Berthoz, Phan, Corcos, & Bungener, 2008 ;Dumas et al, 2002 ;Johnson, Bonn-Miller, Leyro, & Zvolensky, 2009 ), and opiates ( Zijlstra, Veltman, Booij, van den Brink, & Franken, 2009 ). Regardless of whether low hedonic capacity may confer risk to other drugs of abuse, the current study suggests that this trait may be an important variable to identify youth at risk for smoking.…”

“…Given the low odds ratio and evidence that schizophrenia is a neurodevelopmental disorder, the most scientifically conservative stance is that the association between cannabis and psychotic disorders is not causal. As described by Dumas et al (2002), there are three possible models explaining the cannabis-schizotypal link: (1) cannabis use increases risk for schizotypal traits; (2) schizotypal traits increase risk for cannabis use; (3) a third causal variable underlies both cannabis use and schizotypal traits.…”

“…Para cada una de ellas se solicitó información de la edad de inicio del consumo en años, el tiempo de consumo en meses y los días de consumo en el último mes. Estas preguntas fueron formuladas atendiendo a trabajos previos (Dumas et al, 2002;Najolia et al, 2012) y escalas previamente validadas (Soto-Brandt et al, 2014).…”

“…Trabajos previos que analizan el papel de los rasgos negativos de la esquizotipia o las experiencias psicóticas negativas de tipo atenuado, encuentran resultados similares aunque inconsistentes. Por ejemplo, algunos estudios reflejan la existencia de asociación entre la dimensión negativa y el consumo a nivel subclínico (Bailey y Swallow, 2004;Davis et al, 2013); no obstante, es igualmente cierto que otros estudios hallan que los consumidores de cannabis y alcohol presentan menores puntuaciones en la dimensión negativa en comparación con los no consumidores (Nunn et al, 2001;Skosnik et al, 2008) o no encuentran tal asociación (Barkus et al, 2006;Dumas et al, 2002;Fridberg et al, 2011;Schiffman et al, 2005). En términos generales, estos resultados parecen indicar que existe un patrón de asociación diferenciado entre este conjunto de experiencias y rasgos psicóticos subclínicos y el consumo de sustancias (p.…”
