Why did tobacco use among teens begin to decrease after 1998?

Tobacco use among teens began to decrease after 1998 primarily due to increased awareness of the health risks associated with smoking, driven by public health campaigns and education. The landmark Master Settlement Agreement in 1998 led to restrictions on tobacco advertising and marketing, particularly aimed at youth. Additionally, the rise of anti-tobacco legislation and the introduction of cessation programs contributed to this decline. Together, these efforts helped shift social norms and reduce accessibility, making smoking less appealing to teenagers.
