Each year in the U.S., about 30 million hospitalizations occur in individuals 18 and older. Of these, more than 7 million are current cigarette smokers whose average hospital stay is several days. Researchers say that starting smoking cessation therapy during hospitalization and maintaining high adherence post-discharge can markedly improve permanent quit rates in these patients with minimal to no side effects. Cessation therapy also should include long-term counseling and at least 90 days of a prescription drug, specifically, varenicline.
Adolescents who vape cannabis are at greater risk for respiratory symptoms indicative of lung injury than teens who smoke cigarettes or marijuana, or vape nicotine, a new University of Michigan study suggests.

Toxicological Sciences continues to feature leading toxicology research in the areas of developmental and reproductive toxicology; endocrine toxicology; neurotoxicology; molecular, biochemical, and systems toxicology; and more.
February Issue of the American Journal of Public Health Special Section focuses on the impact of E-Cigarettes.
New research suggests the toxic effects of nicotine on the kidneys’ filtering function are partly responsible for the progression of diabetes-related kidney disease in people who smoke. The study is published ahead of print in the American Journal of Physiology-Renal Physiology.
According to the Surgeon General, 14% of Americans smoke and 16 million suffer from smoking-related diseases. Pulmonary fibrosis, a debilitating disease often caused by tobacco usage, is little-known among smokers. The Pulmonary Fibrosis Foundation shares insights on critical risk factors.
Scientists at Wake Forest School of Medicine have found that nicotine promotes the spread of breast cancer cells into the lungs.
Early results of an experimental vaping study have shown significant lung injury from E-cigarette (eC) devices with nickel-chromium alloy heating elements. The findings were consistent, with or without the use of nicotine, vitamin E oil or tetrahydrocannabinol (THC), which have previously been thought to contribute to the life-threatening respiratory problem.
Scientists at Sanford Burnham Prebys Medical Discovery Institute, Camino Pharma, LLC and University of California San Diego School of Medicine have been awarded an $11.4 million grant from the National Institute on Drug Abuse (NIDA) at the National Institutes of Health (NIH) to advance a novel drug candidate for nicotine addiction into first-in-human Phase 1 studies. The drug targets a neuronal signaling pathway underlying addictive behaviors, and would be a first-in-class medication to help people quit smoking.
Most doctors misperceive the risks of nicotine, the addictive chemical in tobacco products, according to a Rutgers-led national survey.
Animal studies suggest that nicotine may be a key chemical responsible for long-term effects associated with maternal cigarette smoking and increased risk of adverse health consequences in the offspring. However, postnatal outcomes of nicotine exposure from maternal use of e-cigarettes…
Researchers at Wake Forest School of Medicine have discovered that nicotine promotes the spread of lung cancer cells into the brain, where they can form deadly metastatic tumors. The study, which will be published June 4 in the Journal of Experimental Medicine (JEM), suggests that nicotine replacement therapies may not be suitable strategies for lung cancer patients attempting to quit smoking. In addition, the researchers show that the naturally occurring drug parthenolide blocks nicotine-induced brain metastasis in mice, suggesting a potential therapeutic option in humans.
The use of e-cigarettes, vapes and mods have increased as smokers liken these alternatives as healthier and not having the same side effects of traditional cigarettes. Because e-cigarettes are readily available over the internet, unlike the sale of cigarettes, it perpetuates the notion that these are a safer alternative. A new study, “The New Era of Nicotine: Better for Patients?” released as part of the American Academy of Orthopaedic Surgeons’ (AAOS) Virtual Education Experience found that smokers and non-smokers believe the use of e-cigarettes and other smoking alternatives have less of an impairment on bone fracture healing than smoking traditional cigarettes, when in fact the nicotine found in both cigarettes and e-cigarettes can impede the healing process.
Lactating mothers who use e-cigarettes or nicotine replacement therapies may be putting their breastfed babies at risk for skull defects, a new study in animals suggests.
Findings from a new animal study suggest that maternal nicotine exposure during breastfeeding could be linked to problems with skull and face development.
Misuse of prescription benzodiazepines (such as alprazolam or Xanax, and diazepam or Valium) has been linked to nicotine use. Evidence of how nicotine “sets up” a craving for benzodiazepines — often called “benzos” — in animal laboratory studies has been published in the open access journal eNeuro.
Article title: COX-2 derived prostaglandins as mediators of the deleterious effects of nicotine in chronic kidney disease Authors: Sunil Rangarajan, Gabriel Rezonzew, Phillip Chumley, Huma Fatima, Mikhail Golovko, Wenguang Feng, Ping Hua, Edgar A. Jaimes From the authors: “In these studies,…
Current policies that include restrictions on the sale of menthol flavored tobacco and nicotine products are less likely to reach those that would benefit from them the most, according to new research from the University of Kentucky’s College of Medicine.
E-cigarettes — especially flavored vaping products — are becoming more popular among teens.
Vaping can cause serious health issues in teens, including e-cigarette or vaping product use-associated lung injury (EVALI), and impaired brain development. Vaping can also put teens at an increased risk of developing other addictions too.
Parents can talk with their kids about the dangers of vaping in a non-judgmental way. Pediatricians can also help by providing parents and teens with information and resources.
Vaping-associated lung injury is a condition characterized by lung inflammation and damage that can lead to respiratory failure and death. Symptoms include shortness of breath, cough, and chest pain, as well as fatigue, fever, and weight loss. Many patients report gastrointestinal symptoms too.
Healthcare experts are urging people to avoid vaping because the exact cause of vaping-associated lung injury is unknown.
People who are using vaping products — especially young people, who have been most frequently affected by the condition — should closely monitor their health and seek immediate medical care if they develop symptoms.
CFR In Brief by Claire Felter. An outbreak of a lung illness linked to vaping is raising the pressure on countries to rein in the booming e-cigarette industry.
“We were seeing a real drop-off in youth smoking, but now we’re seeing an increase,” says Dr. Beth Ebel, a UW Medicine pediatrician and researcher with the Harborview Injury Prevention and Research Center. Among teens as young as middle-school age, vaping with products that have nicotine “predisposes you to cigarette smoking later on.”
Nicotine, once derived from tobacco plants to kill insects, works by altering the nervous system. “We’ve used it, refined it, concentrated it, and now we have a pure form of one of the most addictive substances known,” Ebel says in downloadable video soundbites (2:22).
