According to researchers, teenage girls who diet are more likely to embark on unhealthy behaviors, such as binge drinking, smoking and skipping meals.
A new study reveals researchers have identified areas of the brain which are different in those who regularly smoke and drink alcohol. Researchers discovered the medial orbitofrontal cortex, an area of the brain implicated in reward, has higher functional connectivity in drinkers. In those who smoke, the lateral orbiotfrontal cortex, an area of the brain linked to impulsive behavior, has lower functional connectivity. The study suggests nicotine may increase overall brain connectivity, which may lead to increased smoking behaviors.
Disputing other findings, researchers report there is no direct link between inflammation and depression. The study reports depression may only have a link to inflammation as a result of specific lifestyle features, such as smoking or obesity.
Between 60-90% of people with schizophrenia smoke, compared to between 15-24% of the general population.

Researchers also reported a significant number of participants sustained their reduction in smoking or completely stopped smoking at the end of the 12-week study.
Researchers have engineered a new enzyme that breaks down nicotine in the bloodstream before it reaches the brain. The treatment reduces the urge to smoke and reverses signs of nicotine dependence, preventing relapse.
Our moods, sleeping patterns, smoking status and how easily we tan may be traced back to our Neanderthal DNA, Max Planck Institute researchers report.
Researchers have identified a genetic variant associated with an increased risk of nicotine dependence.
