There is also considerable evidence that individuals engage in heavy and high-risk drinking as part of celebrations or in response to very positive emotions (Del Boca et al. 2004; Kornefel, 2002). More generally, very positive affect increases risk-taking behaviors, including drug use, sexual encounters and gambling (Cyders & Smith, in press; Holub et al., 2005; Kahn & Isen, 1993; Yuen & Lee, 2003; Zapolski et al., 2007).
