Teenagers who use cannabis daily before the age of 17 are more than 60% less likely to complete high school or university, research published in Lancet Psychiatry found. The researchers called for their findings to be considered in cannabis legalisation reform. Alex Wodak of the Australian Drug Law Reform Foundation said the evidence for the harms of frequent use in the study was "compelling" but added daily use before age 17 would be "pretty uncommon". Many studies show that prohibiting cannabis did not make it any less easy for young people to get hold of it.
