Almost 20,000 children in Scotland start smoking every year, according to research by a cancer charity.
Young people aged 11 to 15 are picking up the habit at a rate of 19,900 each year, according to figures released by Cancer Research UK.
The charity has called on the Scottish Government to act quickly on its pledge to introduce legislation on plain packaging for cigarettes. A similar move by the UK Government was put on hold earlier this year.
The charity claims research shows that packaging without branding is less appealing to children.
Vicky Crichton, the charity's senior public affairs manager in Scotland, said: "Smoking is a serious problem in Scotland with almost 20,000 children, tempted by glitzy, slickly designed packs, being lured into starting smoking every year. It is an addiction that is often life-long and kills more than 4,000
"If the Scottish Government is serious about curbing the death toll caused by this lethal habit and meeting its goal for Scotland to become a nation free from tobacco by 2034, then swift action needs to be taken."
A Scottish Government spokeswoman said: "The Scottish Government is committed to introduce standardised packaging, based on the strong evidence to support the impact it will have on preventing young people from starting to smoke. We will identify an appropriate timescale to introduce legislation on standardised packaging to the Scottish Parliament."
The latest figures are based on rates in the Survey of Smoking, Drinking and Drug Use among Young People in England carried out by the NHS Information Centre for Health and Social Care.
Statisticians at Cancer Research UK produced figures for Scotland and the rest of the UK, based on 2011 population estimates.
Eight out of ten adult smokers start the habit by the age of 19 and more than a quarter (27%) of all under 16s - the equivalent of one million children across the UK - have tried smoking at least once, according to the charity.
