A new study that estimated the effects of risk factors for black and white men and women found that black men were reincarcerated more often and more quickly than all others, despite having lower risk scores on nearly all of the variables on a standardized tool that assesses risk.
Now, researchers in the Center for Alcohol Research in Epigenetics at the University of Illinois at Chicago report in the journal Neuropharmacology, that alcohol blocks a potassium channel called KCNK13 that sits within the membrane of dopamine-releasing neurons in the VTA. When the potassium channel gets blocked, the neurons increase their activity and release more dopamine.
As the number of Americans who regularly use cannabis has climbed, so too has the number of those experiencing cannabis withdrawal symptoms. A new study finds that 12 percent of frequent marijuana smokers experienced Cannabis Withdrawal Syndrome (CWS), which includes emotional, behavioral and physical symptoms.
Creatinine elevations, commonly seen during intensive blood pressure (BP) lowering, most likely do not represent true kidney disease, but may instead reflect benign reductions in kidney blood flow that occur naturally during treatment. The findings, published in Annals of Internal Medicine, represent a major advancement in the understanding of whether kidney tissue damage accompanies the diagnosis of chronic kidney disease (CKD) during hypertension therapy.
In a randomized, placebo-controlled study, researchers from Israel have shown that cannabis can produce clinical remission in up to 65 percent of individuals after eight weeks of treatment, but that this improvement does not appear to result from a dampening down of the underlying inflammatory process.
A new Florida State University College of Medicine study in mice produced results that suggest nicotine exposure in men could lead to cognitive deficits in their children and grandchildren. Further studies will be required to know if the same outcomes seen in mice would apply to humans.
Adolescents and young adults who used new pod-based electronic cigarettes commonly did so along with other e-cigarettes and traditional cigarettes.
Teens and young adults who use Juul brand e-cigarettes are failing to recognize the product's addictive potential, despite using it more often than their peers who smoke conventional cigarettes, according to a new study by researchers at the Stanford University School of Medicine.
E-cigarette brand JUUL's Twitter handle is attracting adolescents to the point that at least a quarter of its followers appear to be under age 18. Many of these minors -- to whom it is illegal to sell nicotine-delivery products -- are retweeting JUUL's messages, amplifying its advertisements.
Men and women who lived under communist regimes during the Cold War drink more alcohol more often than people in capitalist nations in the West, according to new research from the University of Kent.
