Teenagers who smoke marijuana daily are
60% less likely to complete high school
60% less likely to graduate college
7x more likely to attempt suicide
than those who never use.
Earlier today (9/9/2014) The Washington Post released the results of a new study in the The Lancet Psychiatry, a British journal of health research. Reporter, Christopher Ingraham, charted the findings below with these notes:

According to the study, there are significant relationships between cannabis use and high school graduation, college graduation, suicide attempts, cannabis dependency (not wholly surprising), and other illicit drug use.
The chart plots the odds ratios of the frequency of cannabis use on various outcomes, compared to not using cannabis at all. A value of 1 would indicate equal odds of a given outcome, 2 would indicate an outcome twice as likely as you’d get from not using cannabis at all, and a value less than 1 would indicate decreased odds of a given outcome.
So for instance, a person who uses cannabis less than monthly would have slightly lower odds of graduating high school or getting a college degree, compared to a person who doesn’t use at all. Increased use further decreases this likelihood. On the other hand, a person who uses cannabis monthly would have roughly 4 times the likelihood of becoming dependent on cannabis as a person who doesn’t use at all.
