CDC’s Office on Smoking and Health has released the following tobacco-related article in the journal, Addicted Behaviors

During the E-cigarette, or Vaping, Product Use-Associated Lung Injury (EVALI) outbreak, patient data on tetrahydrocannabinol (THC)-containing e-cigarette, or vaping, product (EVP) use was collected, but data on product use among non-affected adults after the onset of the EVALI outbreak is limited.  This study describes adult THC-EVP use among adults after EVALI began.

Among adults from a geographically diverse sample of 18 states who reported use of THC-containing EVPs after the onset of the EVALI outbreak, but who did not develop EVALI, almost half reported daily or weekly use.  Respondents reported obtaining products through both informal and formal sources — even after EVALI began.  Respondents odds of daily use and accessing THC-EVPs through commercial sources were higher among states with legalized nonmedical adult marijuana use, compared to states without.  Given the potential for future EVALI-like outbreaks, it is important to monitor the use of THC-EVPs and ensure effective education activities about associated risk.
