Pain and Substance Abuse Interact in a Vicious Cycle
Being in pain and taking illicit substances can lead to a vicious cycle that ultimately worsens and maintains both addiction and pain. ... Read More...
Different Brain Areas Linked to Smoking and Drinking Behaviors
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. ... Read More...
Higher Levels of Nicotine May Help Smokers Quit
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.... Read More...
Making Mice Lose Weight by Imitating Effects From Cold and Nicotine
By stimulating cold and nicotine receptors, researchers successfully improved metabolism in mice, helping them to lose weight. Further studies will investigate whether the same results can be achieved in humans. ... Read More...
Engineered Enzyme Eliminates Nicotine Addiction in Preclinical Tests
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.... Read More...
Dads’ Nicotine Use May Cause Cognitive Problems for Children and Grandchildren
Researchers report a father's exposure to nicotine may have lasting effects on the cognitive development of his offspring. The study reports nicotine exposure may cause epigenetic alterations in key genes within the father's sperm, affecting not only his direct children but also grandchildren.... Read More...
Genetic Mutation Makes it Hard to Quit Smoking
Finding it difficult to quit smoking? Your genes may be to blame. Researchers discover genetic mutations play a key role in nicotine relapse.... Read More...
Differences Between Combined and Isolated Cannabis and Nicotine Use on Brain Networks
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.... Read More...
Researchers Develop Drugs with Potential to Curb Smoking
Researchers have developed more than a dozen new potential drug candidates they believe have the potential to curb smoking addiction by slowing how nicotine is broken down in the body.... Read More...
