The examine was printed Tuesday within the journal World Psychiatry and centered on COVID-19 “breakthrough” infections in totally vaccinated folks identified with substance use dysfunction (SUD), a situation that includes uncontrolled dependence on substances together with marijuana, alcohol, cocaine, opioids and tobacco. Whereas breakthrough infections had been seen in 3.6 p.c of vaccinated folks with out SUD, the examine discovered that 7 p.c of these with SUD had breakthrough infections.

The researchers famous that, regardless of the apparently elevated threat of breakthrough infections, the general fee of an infection in totally vaccinated folks with SUD was nonetheless low when in comparison with the unvaccinated.
“In the beginning, vaccination is very efficient for folks with substance use issues, and the general threat of COVID-19 amongst vaccinated folks with substance use issues could be very low,” NIDA Director Dr. Nora D. Volkow, one of many examine’s lead authors, stated in an announcement. “We should proceed to encourage and facilitate COVID-19 vaccination amongst folks with substance use issues, whereas additionally acknowledging that even after vaccination, this group is at an elevated threat and will proceed to take protecting measures towards COVID-19.”
