It would be much harder for teen-agers to “light up” if a bill passing the House makes it through the legislative session this year. Stores selling cigarettes are targeted by the bill sponsored by Representative Thomas Hoppe of Kansas City. The bill would impose a $250 fine and five-day suspension of its tobacco license upon the fourth violation of its prohibition to sell cigarettes to juveniles. It makes it illegal for those under 18 to buy or possess cigarettes, though violators won’t serve jail time. The bill has its detractors, who believe it reaches too far in its effort to cut Missouri’s high rate of juvenile smoking. The debate now moves to the Senate.
