Harmful Metals Found In Vapors From Tank-style Electronic Cigarettes

The concentration of metals in electronic cigarette aerosols — or vapor — has increased since tank-style electronic cigarettes were introduced in 2013, scientists at the University of California, Riverside, have found[1]. Electronic cigarettes, which consist of a battery, atomizing unit, and refill fluid, are now available in new tank-style designs, equipped with more powerful batteries […]

Cigarette Smoke Makes MRSA Superbug More Drug-Resistant

Cigarette smoke can cause MRSA bacterial strains to become more resistant to antibiotics, new research from the University of Bath indicates. Furthermore, cigarette smoke exposure can make some strains of Staphylococcus aureus – a microbe present in 30-60% of the global population and responsible for many diseases, some fatal — more invasive and persistent, although […]

E-cigarettes Cause Stress-induced Damage In Neural Stem Cells

Electronic cigarettes, often targeted to youth and pregnant women, cause a stress response in neural stem cells, critical cells in the brain, reports a research team at the University of California, Riverside. Using cultured mouse neural stem cells, the UC Riverside researchers identified the mechanism underlying electronic cigarette-induced stem cell toxicity as “stress-induced mitochondrial hyperfusion,” […]

Neonatal Nicotine Exposure Alters Brain’s Reward Circuity

Early life exposure to nicotine alters neurons in the brains of newborn mice, increasing their preference for the drug in later adulthood, researchers at University of California San Diego School of Medicine report. Exposure to nicotine in the first few weeks of life (through maternal lactation) caused a form of neuroplasticity that resulted in increased […]

Metformin May Help With Nicotine Withdrawal Symptoms

The type 2 diabetes drug metformin could potentially be used for treating nicotine withdrawal for people trying to quit smoking, a new study by researchers at the University of Pennsylvania and Johns Hopkins University School of Medicine indicates. The study, carried out in mice, explored whether metformin could ease nicotine withdrawal symptoms. Prior research has […]
