Impact of the COVID-19 pandemic on substance use and dependence: new risks and challenges

The COVID-19 pandemic is a stress factor for the general population and has been associated with an increase in mental illnesses and psycho-active substance use disorders. Evidence indicates that there has been a switch in the pattern of use and choice of drugs, with increased use of licit substances such as alcohol. The population with substance use disorders is known to be particularly vulnerable, and this status may be worsened by the current pandemic, with increased risk of infection and severe illness. It is important that health services adapt to the new risks and challenges that this population faces.
