On World Health Organization World Mental Health Day, PreVenture would like to highlight the importance of prevention. SAMHSA estimates that the average effective school-based program would save an estimated $18, per $1 invested. PreVenture is an evidenced-based mental health and substance-use early intervention recognized by the WHO, the US Surgeon General, UNESCO and the UNODC. The program is currently being implemented in schools and community settings across North America, Europe, Asia and Australia.
