The study showed that patients who received a standard prescription size with a lower default dose of opioids had similar pain control, but took home f...
A new study led by UCL and King's College London researchers found that adolescents are three times more likely to develop a cannabis addiction than adults. However, they do not appear to be at increased risk of subclinical depression or anxiety. In contrast, adult users who become addicted may experience worsening mental health symptoms.
A new Series published in The Lancet estimates that adopting proven road safety interventions targeting four key risk factors could prevent between 25% and 40% of all fatal road injuries worldwide every year. This could save up to half a million lives annually, with increased focus on low- and middle-income countries.
