Community-based interventions showed some impact in a systematic review (Stockings et al, 2018, 24 trials, n=249 125, samples subject to high-risk bias) in:

• reducing risky drinking (AUDIT ˃8, 3 trials, RR 0.78, 95% CI 0.62 to 0.99).

Community-based interventions showed no significant impact in a systematic review (Stockings et al, 2018, 24 trials, n=249 125, samples subject to high-risk bias) in:

• reducing binge-drinking (5 trials, RR 0.97, 95% CI 0.98 to 1.06); and
• reducing 12 month marijuana use (2 trials, RR 0.98, 95% CI 0.86 to 1.11).

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 that:

• universal school-based multiple risk behaviour interventions may be effective in preventing illicit drug use (OR 0.74, 95% CI 0.55 to 1.00; n=5 studies; 11,058 participants; low-quality evidence) at up to 12 months' follow-up

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)

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 that:

• universal school-based multiple risk behaviour  interventions were beneficial in preventing alcohol use (OR 0.72, 95% CI 0.56 to 0.92; n=8 studies; 8751 participants; bothmoderate-quality evidence) at up to 12 months' follow-up
