As marijuana gains global acceptance for medical and recreational use, many adults continue using it into their 30s. Recent research from The University of Queensland raises concerns about its long-term effects beyond age 30.

The study found that people who used marijuana after 30 scored lower on measures of success compared to those who quit or never used it. This analysis included data from over 8,000 mothers and 2,000 children, focusing on impacts at ages 21 and 30.

Prolonged marijuana use may impair cognitive functions like memory and concentration, affecting career and academic success. Financial stability can also be hindered by regular marijuana use, impacting savings and financial goals.

Additionally, marijuana may strain personal relationships if it interferes with responsibilities or communication. Despite these findings, it’s important to note the study’s limitations, including its focus on women and older data.

Overall, the research highlights potential risks of long-term marijuana use and the importance of considering individual circumstances and moderation.
