This study aimed at investigating the association between different profiles of cannabis smoking and the development of covert (non-violent fonns of delinquency that are concealed and sneaky by nature) and oveli (direct confrontation with the victim) antisocial behaviours. It was hypothesized that high cannabis consumption would have differential effects on the two types of antisocial behaviours, by 1) decreasing the likelihood of overt antisocial conduct, ànd 2) increasing the likelihood of co vert antisocial conduct. A sample of 792 male Caucasian participants from low SES neighbourhoods was followed from lOto 17 years of age as part of the Montreal Longitudinal and Experimental Study. Using logistic regression analyses, it was found that early initiation of cannabis smoking during adolescence increased the risk to show both types of antisocial conducts later in adolescence. These associations, however, did not subsist after controlling for initial (preadolescence) level of antisocial behaviour, deviant peers affiliation, alcohol and hard drugs consumption, and family adversity. These results indicated that the association between cannabis consumption and antisocial conduct was spurious, that is, explained by confounded variables, mainly deviant peers affiliation and alcohol drinking. These results do not support a general, direct causal link between cannabis use and the development of antisocial conduct. The absence of main effect and the implications for future research are discussed.
