Chewing Tobacco Linked to Higher Diabetes Risk in New Study

A recent Swedish study has highlighted the risks of chewing tobacco for blood sugar control. The research found that products like snus raise the likelihood of type 2 diabetes by reducing insulin sensitivity. Even short-term use can push blood sugar levels higher, with nicotine playing a key role. Chewing tobacco contains a high concentration of nicotine—around 12.5 milligrams per gram. For comparison, tomatoes, which belong to the nightshade family, hold only about 7 nanograms of nicotine per gram. To match the nicotine in a single gram of chewing tobacco, someone would need to eat roughly 10,504 average-sized tomatoes.

Beyond nicotine, chewing tobacco also includes added sugar, much like regular gum. This combination further disrupts blood sugar regulation. The product also elevates cortisol, a stress hormone that contributes to higher glucose levels over time. The findings are particularly relevant to those managing diabetes. Wil Dubois, an author with type 1 diabetes, has written extensively on the condition. Based in Las Vegas, New Mexico, he lives with his family and cats while advocating for better diabetes awareness.

The study confirms that chewing tobacco affects blood sugar in both immediate and long-term ways. Its nicotine content, added sugars, and cortisol-boosting effects create a triple threat for metabolic health. Those concerned about diabetes risk may need to reconsider its use.
