SEATTLE — Washington state marijuana enforcement officials say they’re beginning undercover sting operations to make sure legal pot stores aren’t selling to anyone under 21.

The Liquor Control Board announced Tuesday that this month it’s starting the sting operations, using 18-to-21-year-old men and women who are employees of the state agency.

The board says it wants to make sure the stores are checking IDs, and that good practice is to ask for identification from anyone who appears to be under 30 years old.
