"Smoking affects the brain," said Bogdan Petre, lead author of the study and a scientist at Northwestern University Feinberg School of Medicine.
"We have found that it affects the way the brain responds to back pain and makes individuals less resistant to an episode of pain."
The scientists detail that the medial prefrontal cortex and the nucleus accumbens play an important role in the development of chronic pain, that is, tobacco consumption strengthens the relationship between these two areas, which makes a person less resistant to chronic pain. .
