The university of virginia link from February talks about possible risks from vaping that I don't remember being highlighted before
"Potential Significant Health Effects of E-Cig Use
In a recently published pilot study, UVA researchers found that although young vape users have a normal CT lung scan and PFT, the HXeMRI revealed they had decreases in gas uptake by tissue and blood. “In order to compensate for this, they were flowing double the amount of blood to catch oxygen,” notes Shim.
Given vaping’s widespread use and immense popularity among teenagers and young adults, there is major concern over its long-term health impact.
In their pilot study, the UVA researchers write, “We anticipate that HP129Xe MRI can help characterize early-stage pulmonary pathophysiology in three distinctive microcompartments of the e-cigarette users’ lungs: airspaces, alveolar-interstitial tissues, and capillaries. This knowledge can inform us about subclinical but potentially significant health effects related to e-cigarette use.”
Enrolling E-Cig Users in a Pivotal Study
Along with Duke University, UVA Health is actively recruiting 21- to 30-year-old e-cig users for a 2-year study using HXeMRI to look for lung damage from vaping. The Duke and UVA research group has also applied for NIH funding to do a 5-year trial to further assess e-cig’s long-term pulmonary impact.
Shim says, “I think the FDA is really interested in these studies, which are needed before health warnings can be added to e-cigs that are marketed as a ‘safe’ alternative to cigarette smoking. It took 30 years of research before warning labels were put on regular cigarettes. Hopefully, with better diagnostic technology it won’t take that long with e-cigs.”
