Playing devil's advocate here.
Ever consider how many tomatoes and potatoes you would have to consume to equate to how much nicotine you would get from vaping or smoking?
Nicotine can have "bad" effects depending upon how much you consume. It is a stimulant and vasoconstrictor, which could be considered to be unhealthy and even dangerous to use should one already have coronary heart disease, peripheral artery disease, hypertension, diabetes, or had a stroke. At extremely high doses it could be considered a poison; in fact it is to this day used as an insectacide.
Just clearing the air that nicotine is not as safe as some here are claiming. There's a risk involved if you drink water or breath air, too.
Agree, but there are people who pour alcohol down their throat daily and then point at us for vaping. Go figure.
Vasoconstriction is one reason I vape 3mg nic levels in my DIY juice. Not vaping is healthier than vaping, but vaping is far better than smoking. We all choose our own poisons. Caffeine is another health concern for those with circulation issues.
I recently had my neck arteries scanned and they were fine. The doctor termed them as "wide open". The medical term is "patent". My last CT scan showed my coronary arteries to be only mildly calcified ... normal for my age. My legs are a different story, though.
