⚠️ Study Limitations — Read These Before Panicking

• Not a human study. The experiments were done in lab-grown cells, tissue slices, and hamsters. These models show biological mechanisms but can't prove the same effects happen at the same severity in living, breathing human vapers.
• Dosage is unclear. It's difficult to compare lab vapor exposure to real-world vaping patterns. The exposure levels in the study may be higher or lower than what a typical vaper experiences.
• No direct comparison to smoking. This study didn't compare vaping effects to cigarette smoke effects. We know from other research that smoking causes vastly more lung damage than vaping.
• Short time frame. 5 days of exposure and 10 days of follow-up tells us about short-term effects but not about long-term (years) outcomes.
• Single study. While published in a reputable journal, individual studies can have flaws or chance findings. Results need to be replicated by other research groups.
• Doesn't test different vape types. The study doesn't compare different devices, e-liquids, nicotine strengths, or vaping styles — all of which could affect outcomes.
