Family- or individual-level multiple risk behaviour interventions to prevent cannabis use
Summary of the evidence
A recent systematic review (MacArthur et al 2018) of 70 RCTs addressing two or more risk behaviours (with a follow-up period of at least six months) and targetting children up to 18 years of age, found:
- little or no effect of family- or individual-level multiple risk behaviour interventions to prevent cannabis use (moderate to low-quality evidence, with few studies available for comparisson, n≤ 4)
