While many people view smoking weed as a harmless habit, scientists have concerning news for those still smoking into their 30s. Research suggests that prolonged marijuana use, like cigarette smoking, can pose serious health risks. While cigarette smoking is directly linked to lung cancer, smoking marijuana can also cause respiratory issues and may affect brain development, particularly when use starts at a young age and continues into adulthood.
The Risk of Smoking Cigarettes
There is no “safe” number of cigarettes you can smoke per day—every cigarette increases your risk of cancer. A 2021 study involving 229,028 Australian participants found that only 1% of people who never smoked developed lung cancer by age 80. However, the risk rises to 14% for smokers. Here’s how smoking frequency affects lung cancer risk:
- 1-5 cigarettes per day: 7.7% chance of developing lung cancer
- 35+ cigarettes per day: 26.4% chance of developing lung cancer by age 80
It’s important to remember that even secondhand smoke can increase the risk of developing smoking-related cancers, such as lung cancer, meaning that even those who don’t smoke are not entirely safe.
The Overlap Between Weed and Cigarette Smoking Risks
While marijuana and cigarettes differ in many ways, both involve inhaling smoke, which introduces harmful toxins into the lungs. Scientists are continuing to study the long-term effects of regular marijuana use, but respiratory issues and mental health concerns are among the potential risks, especially for users over 30.
Conclusion
Whether it’s cigarettes or marijuana, smoking into your 30s comes with significant health risks. It’s never too late to reconsider your habits and take steps to protect your long-term health.
