A recent study from The University of Queensland suggests that marijuana use beyond age 30 may hinder success in areas like income, education, and happiness. The research followed over 8,000 mothers and 2,000 children, examining marijuana use at ages 21 and 30. While younger users showed no major setbacks, those over 30 experienced “lowered success rates.”
However, the study has limitations. It was conducted on Australian women, so the findings may not apply globally. Success was measured using markers like homeownership and relationship status, which may not reflect everyone’s definition of success. Additionally, the study didn’t account for other drug use, acknowledging that its results could be influenced by “polydrug use” rather than just cannabis use.
