You don’t notice them too much unless your doctor has you get into an MRI machine. Then you can see them, scars… Read more

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… Read more

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… Read more

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,”… Read more

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… Read more
