From New Zealand - Marijuana may raise risk of stroke in young adults, according to a report presented at the American Stroke Association's International Stroke Conference. Researchers examined 160 stroke patients between the ages of 18 and 55. All participants had a urine test upon admission to the hospital. When compared to matched controls, researchers found that these stroke patients were 2.3x more likely to test positive for cannabis in their urine tests.
From London - According to a report published in PLOS Medicine, obesity may cause vitamin D deficiency. Researchers examined the genetic data of nearly 42,000 adults, comparing their results to an additional 123,000 participants. Genetic markers were analyzed to explore the link between BMI and genes associated with vitamin D metabolism. Results showed that a 10% increase in BMI was linked to a 4% reduction in vitamin D concentrations. These results were consistent regardless of gender and age.
