At what age do most individuals typically develop tobacco use disorder?

The most common age for the onset of tobacco use disorder is around 18 years old, which aligns with the findings in addiction studies. This age often corresponds with the legal age at which individuals can purchase tobacco products in many regions, as well as the period when individuals transition into adulthood and are exposed to various social situations that might encourage tobacco use.

Research indicates that the majority of smokers start using tobacco during their teenage years, with a significant number developing dependence shortly thereafter. By the time individuals reach 21, they may already have established patterns of tobacco use, which can evolve into a disorder marked by an inability to control the habit despite knowing its harmful effects.

The later ages presented, such as 30 or 35, are often more relevant to individuals who may begin smoking later in life or who might struggle with tobacco cessation after years of use. However, the onset of tobacco use disorder typically occurs much earlier, reinforcing the importance of preventive measures targeted at younger populations.
