Scientist Joshua Muscat of Penn State University School of Medicine, Hershey, and his colleagues conducted research on whether smokingcigaretteSmoking in the morning can increase the risk of lung, head, and neck cancer. “These smokers have higher levels of nicotine and other tobacco toxins in their bodies, making them more susceptible to addiction than those who smoke about half an hour or more later,” Muscat said.
A survey of 4,755 lung cancer cases, all of whom were smokers, was conducted.cigaretteNormal studies show that, compared to those who smoke 60 minutes after waking up, those who smoke within 31 minutes to 1 hour after waking up have a 1.31 times higher risk of lung cancer, and those who smoke within half an hour after waking up have a 1.79 times higher risk of lung cancer.
A head and neck cancer survey was also conducted on 1,055 head and neck cancer cases and 785 control cases, all with a history of cancer.cigaretteThe study showed that, compared to those who smoked within 60 minutes of waking up, those who smoked between 31 and 60 minutes of waking up had a 1.42 times higher risk of developing head and neck cancer.

Smoking combined with drinking coffee or alcohol increases the accumulation of toxins in the body. (Image: Internet source) |
Researchers at the University of Athens Medical School in Greece conducted a short-term study on 24 people to see the immediate harm of smoking while drinking coffee, and a longer-term study on 160 people to see the long-term harm of combining the two. The participants were smokers and did not have cardiovascular problems, diabetes, high cholesterol, or high blood pressure. The researchers found that combining cigarettes with coffee had more negative effects on cardiovascular health than not combining them at all.
Another American study suggests that 75% of throat, mouth, and larynx cancers are caused by a combination of tobacco and alcohol. People who consume both alcohol and tobacco have a 38 times higher risk of developing these cancers compared to those who do not smoke or drink alcohol.
Thus, combining smoking with drinking coffee or alcohol increases the accumulation of toxins in the body, causing them to deteriorate much more rapidly than if they smoked cigarettes alone.
