(Seattle, WA)  --  A new poll shows many people in Washington favor an increase in the minimum age for buying tobacco products.  The Elway poll of 500 registered voters in the state shows 65-percent favor raising the minimum age to 21.  Lawmakers have introduced bills to that effect, which also apply to purchases of "vaping" products.  Similar legislation failed to pass last year, but state Attorney General Bob Ferguson says it has more momentum this year.
