"Interestingly, our results do not confirm our hypothesis of better overall functioning among abstainers. In fact, what our research indicates is that the main difference between COG [cannabis use only group] youth and abstainers [those abstaining from all drugs] is that the former are more socially driven: they are significantly more likely to practice sports, and they have a better relationship with their peers. Moreover, even though they are more likely to skip class, they have the same level of good grades; and although they have a worse relationship with their parents, they are not more likely to be depressed. Nevertheless, our results seem to indicate that, although typical of the adolescence process, having good support from friends together with a less solid relationship with parents is a risk factor for occasional cannabis use."
