A smoking cessation drug called cytisine may be a helpful new tool for the treatment of Parkinson's disease in women. Cytisine was found to reduce the loss of dopamine neurons. The effect was more pronounced when estrogen was present.
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 report if specific neurons in the VTA which are active both when using and withdrawing from nicotine.
Researchers say those who use both cannabis and nicotine have greater brain connectivity that those who take one or the other. The networks of those who used both substances closely resembled those who people who took neither drug.
Common green apple flavorant farnesene enhances nicotine reward in mouse models. The flavorant is also rewarding on its own. Researchers say with or without nicotine, flavored vapes, especially those containing farnesene, pose potential neurological risks, including addiction.
A new study reports coupling menthol with nicotine acts to desensitize receptors in the lungs and airways.
Researchers determine how small changes in a particular region of the genome can alter nicotine consumption.
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.
Researchers have developed two caffeine based compounds that show promise in the fight against Parkinson's disease.
Mixing traditional cigarettes with vaping products is as detrimental to health as smoking cigarettes alone, a new study reports.
