Marijuana use is becoming increasingly accepted for both medical and recreational purposes, but a recent study suggests that adults over 30 may want to reconsider. Researchers from The University of Queensland found that continued marijuana use past age 30 is associated with reduced success in areas such as income, education, and overall happiness.

The study tracked over 8,000 mothers and 2,000 children, examining drug use at ages 21 and 30. While younger users showed no significant disadvantages, those over 30 experienced noticeable declines in “success markers.”

However, the research has limitations. Conducted on Australian women, its findings may not apply universally. Success was measured through factors like homeownership and relationship status, which may not align with everyone’s values. Additionally, the study did not account for other drug use, acknowledging that results might reflect “polydrug use” rather than cannabis alone.

In summary, moderate marijuana use may not hinder your future, but excessive use as you age could impact your career, relationships, and stability. If it’s starting to disrupt your responsibilities, it may be worth reconsidering your habits.
