2: Research suggests vaping is bad for your heart and lungs. It causes you to crave a smoke and suffer withdrawal symptoms if you ignore the craving. Nicotine is a toxic substance. It raises your blood pressure and spikes your adrenaline, which increases your heart rate and the likelihood of having a heart attack.

Researchers at the University of California, San Diego, have now established a link between anticholinergics and mild cognitive impairment, which can lead to dementia, including Alzheimer’s disease.
Where does Alzheimer's degeneration begin?
In the first hit, she explains, Alzheimer’s biomarkers indicate that degeneration begins in a small region of the brain called the basal forebrain, which produces acetylcholine. “In the second hit, anticholinergic drugs further deplete the brain’s store of acetylcholine,” she says.
