Comorbidity in drug use is one of the most relevant aspects of substance addictions. It is, however, an issue on which there is still not enough scientific research regarding behavioral addictions and the relationship with other addictions, especially in regard to the so-called technological addictions. This paper analyzes the relationship between the main criteria of gambling addiction with that of technology, and tobacco and alcohol consumption in 2,074 adolescents between 14 and 19 years of age who were administered the addiction prevention program to gambling, Ludens. In the case of behavioral addictions, the only high correlations were found between mobile and social network addiction scores. This result is in line with the hypothesis that the existence of comorbidity among behavioral addictions requires the participation of common psychological processes. Besides, the absorption into which people with this type of addiction are imbued is usually incompatible with the presence of other behavioral addictions that also require a high degree of involvement.
