A key argument towards making it straightforward to purchase e-cigarettes is that younger individuals who begin vaping will get hooked on nicotine, and so will find yourself switching to conventional cigarettes for the quicker nicotine hit.

The evaluation can’t rule out, nonetheless, that vaping has a really small gateway impact, says Shahab.

The findings might not persuade all critics of e-cigarettes. “I don’t see this examine as refuting the in depth proof that already exists for a gateway impact,” says Martin McKee on the London College of Hygiene & Tropical Drugs. “Following up people is probably the most applicable method to reply this query.”
