Why can't under 18's buy fags?

Under 18s are prohibited from buying cigarettes to protect their health and reduce the risk of developing lifelong addictions to tobacco. Research shows that early exposure to smoking increases the likelihood of long-term use and related health issues. Many countries have implemented age restrictions as part of broader public health measures to reduce smoking rates among young people. These laws aim to promote healthier lifestyles and prevent the harm caused by tobacco use.
