Marijuana use is gaining acceptance, but a new study suggests adults over 30 might reconsider. Research from The University of Queensland highlights that “continuing marijuana use past 30 is linked to lower success” in income, education, and overall happiness.

Frequent marijuana users were found to have lower income levels compared to non-users, suggesting potential long-term effects on financial stability. The study also reports that ongoing marijuana use is associated with lower educational achievement. Individuals were less likely to pursue advanced education, which can affect career growth and job opportunities.

“Marijuana use past age 30 is associated with lower life satisfaction and happiness,” researchers noted. Users reported increased mental health challenges, possibly due to altered motivation and coping abilities over time. While marijuana use can offer short-term benefits, researchers caution that prolonged use may impact mental and physical health, leading to “increased risk of cognitive decline and addiction.”

This study encourages adults to weigh potential effects on career, health, and well-being when considering long-term marijuana use.
