There will be a public hearing on the legislation Tuesday.

The bill would also add e-cigarettes to the existing smoke-free workplace law and prohibit health care institutions — including pharmacies — from selling tobacco products.

Massachusetts Republican Gov. Charlie Baker said last year he supports banning the sale of cigarettes and other tobacco products to people under 21.
