- People with SUD are 7% to 7.8% more likely to suffer a breakthrough COVID-19 infection
- These Individuals are also more likely to suffer breakthrough hospitalizations and deaths
- People without SUD only have a 3.6% chance of suffering a breakthrough infection
Fully vaccinated people who are also heavy marijuana users may be more likely to suffer a breakthrough COVID-19 infection, researchers found.
In a new study published on Tuesday in World Psychology, researchers found that people with substance use disorders (SUD) or people who have addictions to marijuana, alcohol, cocaine, opioids and tobacco were 7% more likely to be infected with COVID-19 despite being fully vaccinated. The risk increases to 7.8% among people with marijuana use disorder.
In comparison, people without SUD only had a 3.6% chance of suffering a breakthrough COVID-19 infection.
“Patients with cannabis use disorder, who were younger and had less comorbidities than the other SUD subtypes, had higher risk for breakthrough infection even after they were matched for adverse socioeconomic determinants of health and comorbid medical conditions with non-SUD patients,” researchers at Case Western Reserve University in Cleveland wrote.
The researchers also noted that the behavior of those dependent on cannabis may also contribute to the higher risk.
