Correlates and comparisons of use of a variety of drugs and associated harms in various high and middle-income countries

In 2021, COVID-19 continued to confound, and sometimes devastate, our family, social and working lives. We hope for and work towards a less disrupted, peaceful and more environmentally sustainable and equitable 2022. Despite the difficulties faced by researchers around the world, we have remained committed to making important contributions, we have adapted and found better ways to connect virtually, and we have continued to collaborate on projects and co-author papers that increase our understanding of the use of, and harm linked to, alcohol, other drugs and gambling.
