(1) Background: Many public bodies have warned of the increased consumption of cannabis, particularly among adolescents. From the Positive Youth Development approach, the promotion of personal protective factors takes on special importance against some risks, such as the consumption of addictive substances. (2) Methods: This research is one of the first to study the role of trait and ability emotional intelligence in relation to cannabis use and with respect to other personal variables of protection, such as coping styles and assertiveness. For this purpose, a final sample of 799 schoolchildren was obtained. (3) Results: After controlling for age and gender, the results of the regression analyses revealed that emotional perception, emotional facilitation, emotional clarity, emotional repair, active coping style, and assertiveness were inversely and significantly associated with cannabis use behaviors. On the other hand, the emotional attention and avoidant coping style factors were positively and significantly associated with these behaviors. (4) Conclusions: These findings provide new evidence that could be useful in terms of guiding health-promoting clinical and educational interventions at an early age.
