As marijuana becomes more accepted for medical, fun, and stress relief, more research is showing that adults over 30 might need to think about their habits again. Still smoking weed at 30? Check out what science says in this article.
New studies from Australia are showing possible downsides for older cannabis users, which raises questions about how it might affect their lives in the long run.
Smoking Marijuana After 30 Could Impact Your Success
If you’re still smoking weed at 30 and like to enjoy a joint now and then, new research from The University of Queensland might have some serious news for you.

A study looking at the life outcomes of marijuana users found that adults who keep smoking after 30 usually have lower success rates in different areas. These areas include:
- Education
- Income
- Home ownership
- Relationship status
- Reported happiness

Interestingly, the study found these negative impacts only applied to those who continued smoking weed into their 30s, suggesting younger, experimental use might not have the same consequences. However, the researchers caution against overgeneralizing their findings.
Limitations of the Study
Before deciding to completely stop using marijuana, it’s crucial to think about the limits of the study. Although the research offers some interesting points, it has a few drawbacks that could affect how widely it can be applied:
1 – Narrow Demographics
The information comes from a specific group of mothers in Australia. Plus, some of the data is from 1981, which might not show what’s happening in today’s world or with different groups of people around the globe.
2 – Questionable Success Markers
The study looks at things like owning a home and being in a relationship as signs of success, but these can be very personal. What counts as success can change a lot depending on where you live and your culture.
For example, lots of successful people today choose to rent or live a lifestyle where they travel a lot, and being single doesn’t mean you’re failing at life.
3 – Overlap with Other Drugs
The study didn’t really consider how using other drugs might affect the results. The researchers said they didn’t have enough information about other substances, like synthetic drugs or opioids, that could also lead to the negative effects seen in some people.
What Does This Mean for You?
In the end, the research shows that being moderate and aware of your choices is important.
Trying marijuana when you’re young doesn’t automatically ruin your future, but using it too much as an adult could lead to problems you didn’t expect.
Tips for Responsible Use:
- Monitor your motivation levels and performance at work.
- Keep track of your spending habits to ensure cannabis isn’t impacting your finances.
- Make sure marijuana doesn’t interfere with personal relationships or responsibilities.
If you find the habit affecting your life negatively, it may be time to consider cutting back or quitting altogether.
