The legal age to vape varies by country and state. In the United States, the legal age to buy vapes is 21. However, in most countries, the legal age to buy vapor products is usually the same age at which citizens are considered adults, which is usually 18. Some countries have a national legal age, but individual states or provinces are allowed to set legal ages that are higher. In Australia, sales of nicotine-containing consumer products (except cigarettes) are illegal without a doctor’s prescription, but non-nicotine vapes are allowed, and the age to purchase varies from state to state. It is important to note that while federal regulations restrict the sale of tobacco products, including vaping products, to people who are 18 or older, some states have raised the minimum age to 21. It is also important to note that while it may be legal to purchase vapes at a certain age, some states have laws that prohibit the use or possession of vapes by minors.
