Not strictly speaking true. Pure nicotine would be 100% (which is basically rat poison). The highest strength nicotine vape/eliquid you can buy is 2%. Vapes can come in different strength nicotine, including zero. Sadly, shops only seem to sell disposable vapes with 2% nicotine (the max strength) so it's no wonder the latest fad kids are into is getting them into bother. Vaping too much/too quickly is what causes the heart attacks as it's a stimulant and that's how it kills rats (notwithstanding the spiked vapes which are from dodgy sources anyway).
There are only 4 chemicals in a vape (which are still, largely an unknown quantity in terms of harm). A tobacco cigarette has hundreds of carcinogenic chemicals which are known to clog up your arteries and lungs with tar and poisons. It's not the nicotine that does the long term damage - nicotine's only purpose is to get you addicted to a corporate product so they can sell more/make a profit.
I think disposable vapes should be zero nicotine and only available to over 21s although that still wouldn't stop kids doing it, it might stop them becoming addicted to the nicotine
The NHS endorses vaping as a smoking cessation method. It would be nice if it was on prescription but I doubt that will ever happen as it would be basically endorsing a chemical addiction. If it was to be prescribed, would it be put into the same category as methadone for heroin addicts? Even Nicotinell vapes/patches/lozenges are higher nicotine strength than most cigarettes.
As a stop smoking tool, (non disposable) vapes are good because you have more control over the nicotine levels and can reduce it to zero. So then you're just left with the hand to mouth habit and timings (eg after a meal) to overcome.
I shall get off my soapbox now
