Why did people think it was ok to smoke in the olden days?

In the past, smoking was often viewed as a socially acceptable and even glamorous activity, promoted by advertisements and cultural norms. Many people were unaware of the health risks associated with tobacco use, as scientific research linking smoking to serious illnesses was limited or emerging. Additionally, smoking was often associated with relaxation, socialization, and status, making it a common practice in everyday life. This perception persisted until increased awareness of the dangers of smoking began to change public attitudes in the latter half of the 20th century.
