If vaccinated, chances of breakthrough COVID-19 is higher for those who smoke or use substances

A new study reveals that people with substance use disorders are more likely to contract COVID-19 compared to vaccinated individuals who don’t use substances.

580,000 health records for vaccinated people were studied by the National Institute on Drug Abuse.

Data reveals that breakthrough cases among substance users were low, but still higher than those who didn’t use any substances.


A variable, however, shows that many substance abusers have underlying health conditions as well as come from a lower socioeconomic background. These are also responsible for the increased risk of breakthrough infections.

Substance abusers also had a higher chance of greater illness, hospitalization, and death if they did contract the virus.
