Marijuana is becoming increasingly accepted for both medical and recreational use, but a recent study suggests that adults over 30 may want to reconsider long-term consumption. Researchers from The University of Queensland have found that continued marijuana use beyond this age is linked to lower success in key life areas, including income, education, and overall happiness.

The Study’s Key Findings

The study tracked over 8,000 mothers and 2,000 children, examining their drug use at ages 21 and 30. While younger users didn’t exhibit significant setbacks, researchers observed a noticeable decline in success rates among individuals who continued marijuana use into their 30s. The study indicated that prolonged use may impact financial stability, career progression, and personal fulfillment.

Important Caveats to Consider

Despite these findings, there are limitations to the study. For one, it was conducted exclusively on Australian women, which means the results may not accurately reflect patterns in other populations or countries. Additionally, the study used specific markers—such as homeownership and relationship status—to define success, but these factors don’t necessarily align with everyone’s personal definition of achievement.

Another limitation is that the research did not account for other drug use. The study acknowledges that some of the observed effects may stem from polydrug use rather than marijuana alone. This means external factors could contribute to the reported decline in success rather than cannabis use itself.

The Takeaway: Moderation is Key

While occasional marijuana use may not drastically impact one’s future, excessive or prolonged use past the age of 30 could potentially hinder career growth, financial stability, and personal relationships. If marijuana consumption starts interfering with responsibilities, it may be worth reassessing usage habits to maintain a balanced and fulfilling lifestyle.
