Consuming nicotine and alcohol four hours before bedtime causes worse sleep continuity and sleep disruptions. Surprisingly, researchers found no link between caffeine consumption four hours before sleep and sleep disturbances for most people.
Smokers may have reduced neuroimmune function compared to their non-smoking peers. Researchers report restoring the immune system may benefit smokers. Immune dysfunction is linked to cognitive dysfunction.
Meta-analysis finds a two-fold increased risk of developing schizophrenia and psychosis amongst those who smoke tobacco. Researchers speculate nicotine is most likely responsible for the link. They suggest future research looks at the link between e-cigarettes and a possible increased risk of psychosis in young adults, the largest consumer group for the products.
In utero exposure to nicotine could increase the risk of sudden infant death syndrome, researchers report. The findings raise concerns about both smoking and the use of nicotine replacement therapies during pregnancy.
A new study links prenatal smoking with a significantly increased risk of a child developing ADHD later in life. The study found higher cotinine levels in the mother's blood during pregnancy increased the risk of her child being diagnosed with ADHD three fold.
A new study reports chronic nicotine exposure during pregnancy alters the genetics and dopamine neurons of newborns. The findings could help researchers develop a possible cure for nicotine addiction.
Researchers have identified over 500 genetic variants which affect the use of, and addiction to, alcohol and tobacco.
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.
Researchers report allowing smokers to dictate their nicotine intake while trying to quit makes them more likely to succeed. Results suggest most smokers who use nicotine replacement medications can tolerate doses that are four times higher than normally recommended.
