Scientist Joshua Muscat, Penn State College of Medicine, Hershey and his colleagues conducted a study to see if smokingcigaretteMorning smoking can increase the risk of lung, head and neck cancer. “These smokers have higher levels of nicotine and other tobacco toxins in their bodies, so they are more likely to become addicted than those who smoke half an hour or more later,” said Muscat.
A survey of 4,755 lung cancer cases, all of whom were smokers,cigaretteThe study found that compared with people who smoked 60 minutes after waking up, those who smoked within 31 minutes to 1 hour after waking up had a 1.31 times higher risk of lung cancer, and those who smoked within half an hour after waking up had a 1.79 times higher risk of lung cancer.

Researchers at the University of Athens Medical School in Greece conducted a short-term study on 24 people to see the immediate effects of smoking while drinking coffee and a longer-term study on 160 people to see the long-term effects of combining the two. The study participants were smokers and had no cardiovascular problems, diabetes, cholesterol or blood pressure. The researchers found that combining smoking with coffee had a greater negative impact on the cardiovascular system than not.
Another American study found that 75% of cancers of the throat, mouth and larynx are caused by a combination of tobacco and alcohol. People who consume alcohol and tobacco are 38 times more likely to develop cancer than people who do not smoke or drink alcohol.
Thus, smoking combined with drinking coffee or alcohol increases the accumulation of toxins in the human body, causing them to be destroyed much faster than if they only smoked cigarettes alone./.
