Does cannabis cause cancer? Here’s what the study says
A study from the University of Western Australia shows that long-term cannabis use increases the risk of cancer due to cellular and genetic damage. Cannabis, known as a ‘genotoxic substance’, can cause DNA mutations and transgenerational effects, which can affect eggs, sperm and offspring.

A recent study conducted by researchers at the University of Western Australia has revealed a disturbing link between cannabis use and an increased risk of cancerPublished in Addiction Biology, the study shows that long-term cannabis use can cause significant cellular damage, increasing the risk of developing cancer.
The research team has classified cannabis as a ‘genotoxic substance’, meaning it can damage the genetic material within cells. This genetic damage can lead to DNA mutations, which are known to cause rapid aging and contribute to the development of cancer over time. According to the study’s findings, this process may have more far-reaching consequences than previously thought.
One of the most alarming aspects of the study is the revelation of transgenerational effects of cannabis use. Researchers highlight how the damage caused by cannabis use, particularly to eggs and sperm, can be passed on to future generations. This finding is particularly worrisome, as recent studies have linked mitochondrial dysfunction and chromosomal damage to increased cancer risk. Studies show that cannabis interferes with cellular energy production by disrupting mitochondrial function, further exacerbating the problem.
Dr. Stuart Rees, one of the lead researchers at the University of Western Australia, emphasized the profound effects of cannabis on cellular health and its potential to cause lasting damage across multiple generations. For decades, cannabis use has been linked to various health complications, including the development of micronuclei and mitochondrial disruption. Additionally, several studies have established an association between cannabis exposure and developmental disorders, such as autism and cognitive processing difficulties in both humans and rodents.
The study emphasizes the importance of understanding the long-term effects of cannabis consumption. Researchers claim that cannabis consumption accelerates aging at various stages of life, from eggs and sperm to fetuses and adults. This transgenerational effect can manifest in a number of ways, from aging of reproductive cells to potential health problems in offspring. As the study concludes, the consequences of cannabis use may be broader than individual health concerns.
Dr. Rees also called on policymakers to reevaluate their stance on cannabis use, and urged them to consider not only the immediate effects on individuals but the broader implications for future generations. This study serves as an important wake-up call for policymakers, reminding them to approach cannabis use with a full understanding of the potential risks, both personal and generational.
