Two researchers from New Zealand set out to study “Cannabis Use and Later Life Outcomes.” They published the results of their research in a scientific journal called Addiction. Here’s how they described the aim of the study: “To examine the associations between the extent of cannabis use during adolescence and young adulthood and later education, economic, employment, relationship satisfaction and life satisfaction outcomes.”

And here’s how they summarized the results of the study:

The results suggest that increasing cannabis use in late adolescence and early adulthood is associated with a range of adverse outcomes in later life. High levels of cannabis use are related to poorer educational outcomes, lower income, greater welfare dependence and unemployment, and lower relationship and life satisfaction. The findings add to a growing body of knowledge regarding the adverse consequences of heavy cannabis use.
