Following the launch of the Alcohol, Tobacco and Other Drugs Council's "Everybody's Business" framework on Monday, several Tasmanian groups have said the age limit did not need to be reconsidered.

On Monday, ATDC chief executive Jann Smith said the framework would call for a review of the legal drinking age in the state, as well as reviewing the legal blood alcohol level for driving and restricting alcohol at events.

Ms Smith said research into the developmental effects of alcohol would be undertaken but Tasmanian Hospitality Association general manager Steve Old said this research had already been done several times before.

"The legal age should be what it is, there has been a lot of research done and it has shown that the legal age should stay where it is," Mr Old said.

"Everything has already been reviewed copious amounts of times."

Mr Old said that if the legal drinking age were to be increased to 21, this would not only affect those who were consuming alcohol but also those who served it.

"If you say that someone has to be 21 to drink alcohol then everyone who works in the industry also has to be 21 and that would impact a lot of people who need that work," he said.

Launceston's Commercial Hotel licensee Clint Laskey said he also thought the age limit should stay where it was.

"At least if they're in a venue they are being monitored and looked after to a certain extent," Mr Laskey said.

"If they are not allowed to drink at 18 then what else are they going to do, they might choose to drink on the streets and that's worse."

Mr Laskey said the Commercial Hotel introduced a wristband system several years ago, giving a brightly coloured wristband to anyone too intoxicated to be served alcohol.

He said this system had been a success and allowed the business to continue to serve customers but also to ensure the safety of its patrons.
