Nicotine Changes How Nicotinic Receptors Are Grouped on Brain Cells

Nicotine -- the primary compound found within tobacco smoke -- is known to change the grouping of some subtypes of nicotine receptors, but the mechanisms for nicotine addiction remain unclear. This inspired a group of University of Kentucky researchers to explore the role nicotine plays in the assembly of nicotine receptors within the brain. During the Biophysical Society meeting, Feb. 11-15, 2017, Faruk Moonschi will present the group’s work, which centers on a fluorescence-based “single molecule” technique they developed.

Depression Linked to E-Cigarette Use Among College Students

The emergence of e-cigarettes as a nicotine product has left scientists with many questions about their impact on health, including how the product interacts with depression. A new study by researchers at The University of Texas Health Science Center at Houston (UTHealth), published today in Nicotine & Tobacco Research, found a connection between depression and initiation of e-cigarette use among college students.

FDA ad campaign geared toward rural teens who use smokeless tobacco products fails to provide public with important information on relative risks of smokeless tobacco compared to traditional cigarettes, Kozlowski and Sweanor write.

Teens Who Vape at Increased Risk for Future Cigarette Smoking

Among high school seniors who have never smoked a cigarette, those who vape are more than four times more likely to smoke a cigarette in the following year than their peers who do not vape.

Mixing Opioids and Alcohol May Increase Likelihood of Dangerous Respiratory Complication, Especially in the Elderly, Study Finds

Taking one oxycodone tablet together with even a modest amount of alcohol increases the risk of a potentially life-threatening side effect known as respiratory depression, which causes breathing to become extremely shallow or stop altogether, reports a study published in the Online First edition of Anesthesiology.

Study: Toxic Metals Found in E-Cigarette Liquids

A study led by researchers at the Johns Hopkins Bloomberg School of Public Health found high levels of toxic metals in the liquid that creates the aerosol that e-cigarette users inhale when they vape.

Pain During Alcohol Withdrawal: Electroacupuncture May Help

Hyperalgesia refers to an increased sensitivity to pain. It can occur during alcohol withdrawal, and may contribute to a relapse to drinking. Alternative therapies such as acupuncture and electroacupuncture (EA; which combines acupuncture with electrical stimulation) are effective in reducing pain and, possibly, alcohol-withdrawal symptoms. This rodent study investigated whether EA can alleviate hyperalgesia during alcohol withdrawal, potentially reducing the risk of a relapse to drinking, and whether it achieves this effect via action at mu opioid receptors (MORs) located in a brain region called the lateral habenula.

Yale Study: 1 in 4 Teen E-Cigarette Users Have Tried 'Dripping'

Yale researchers found in a study that one in four high schoolers who use electronic cigarettes are inhaling vapors produced by dripping e-liquids directly onto heating coils, instead of inhaling from the e-cigarette mouthpiece, possibly increasing exposure to toxins and nicotine.

Thirdhand Smoke Affects Weight, Blood Cell Development in Mice

A new Berkeley Lab-led study found that the sticky residue left behind by tobacco smoke led to changes in weight and blood cell count in mice. These latest findings add to a growing body of evidence that thirdhand smoke exposure may be harmful.

Mount Sinai Neurobiologist Illuminates the Underexplored Potential of Cannabis to Address Opioid Addiction

A number of animal studies and a small human pilot study have revealed that cannabinoids, extracts of cannabis legally sold as medical marijuana, could reduce cravings and ease withdrawal symptoms in heroin users.
