The Minister for Health is to bring legislation to Cabinet today that will ban the sale of e-cigarettes to under 18s.
The proposals will also make cigarette machines illegal.
If Minister Simon Harris' proposals are given the green light, it will mean major changes for how cigarettes and e-cigarettes are sold here.
E-cigarette retailers will not be allowed to sell to minors.
While around 6,000 cigarette machines in pubs and clubs across the country will disappear.
The Irish Cigarette Machine Operators Association opposes the plans, previously saying it will cost up to 200 jobs.
The Minister is also proposing that a new licensing system for the sale of tobacco and e-cigarettes, which he says will l better reflect "the serious nature of the product to be sold."
Under the current system, a retailer pays a one-off fee - equivalent to the cost of four to five packets of cigarettes - to sell the products.
