Heavy Marijuana Smoking May Increase Cancer Risk

Topic: Health

Researchers at USC found that heavy marijuana smoking may increase cancer risk. They studied people who smoked large amounts of marijuana and found they were more likely to develop lung and head and neck cancers.

Many people think marijuana is safe, but scientists are still learning about its effects on cancer. Brooks Udelsman, a thoracic surgeon at USC Surgery, says that while tobacco smoking is well-known to cause lung cancer, the picture for marijuana is less clear.

A recent study led by Niels Kokot, an otolaryngologist at USC Caruso Department of Otolaryngology -- Head and Neck Surgery, found that people who smoked large amounts of marijuana were more likely to develop small cell lung cancer and non-small cell lung cancer. They also found that daily marijuana users were 3.5 to 5 times more likely to develop head and neck cancers than those who didn't use it.

But how much marijuana is too much? The researchers don't know exactly, but they think there may be minimal risk for occasional or light users.

Why It Matters

This study matters because many people in India are using marijuana, especially young adults. Understanding the risks can help them make informed decisions about their health.
