, young adults aged 18-25 who use nicotine vape products were significantly more likely to experience a range of mental health issues than their non-vaping peers, including depression, anxiety, and rumination or dwelling on negative thoughts, as well as sleep issues like insomnia and emotional problems such as loneliness.
Perhaps the biggest shared characteristic among the vaping group, as Surrey neuroscience lecturer and study co-author Dr. Simon Evans said in the university's press release, was an overwhelming tendency towards anxiety, with a whopping "95.9 percent of users being categorized as having clinical levels of anxiety symptoms."
Important to note: this is a type of research where it's very hard to pin down the relationship between correlation and causation. Are the students anxious because they're vaping, or do anxious kids tend to gravitate to vaping for a variety of social and psychological reasons? It's tough to say, and probably complicated.
