BOSTON (AP) — A handful of Massachusetts lawmakers are hoping to persuade their colleagues to support a proposal that would make the state the first to adopt a ban meant to eliminate the use of tobacco products over time. Other locations have weighed similar “generational tobacco bans.” The bans phase out the use of tobacco products based not just on a person’s age but on birth year. Lawmakers plan to file the proposal next year. If approved, the bill would set a date and ban the sale of tobacco to anyone born after that date forever, eventually banning all sales.
