SACRAMENTO, Calif. -- Some California physicians said they believe the legal age to smoke should be raised from 18 to 21, and a proposal is in the works to put pressure on lawmakers to make it happen.

The proposal would make it illegal for anyone under 21 to buy, possess or receive tobacco products.

Dr. Jack Lewin of the California Medical Association said teens are the main concern.

"We think this particular issue will send a great message. California sets the tone, sets the stage for these kinds of changes for the whole nation. It's time we move the legal age to purchase tobacco up the age of 21," Lewin said.

The American Lung Association estimates that 90 percent of all smokers picked up the habit before age 21.

Medical association representatives said they're not trying to control young people, but are try to prevent them from getting addicted to smoking at an early age.

"It doesn't work for everybody and every kid won't stop smoking, but on the other hand, many kids will because access to tobacco will be tougher," Lewin said.

Some young smokers said they support the proposal.

"Smoking sucks. It's bad for you. I've been smoking since I was 11 and I can't quit," smoker Jenelle Daffron said.

CMA members are scheduled to meet Monday in Southern California to vote on whether to pursue the proposal.

If it is ratified, the association said it will direct its lobbyist to put pressure on lawmakers to consider the plan.
