Maine collected increasing amounts of excise tax revenue from non-cigarette tobacco products like smokeless tobacco from 1998 to 2011, rising from $2.89 million in 1998 to $11.57 million in 2011. In 2005, Maine changed its smokeless tobacco excise tax from a flat rate per unit to a weight-based system of $2.02 per ounce, with a minimum of $2.02 per canister, which contributed to higher and steadier revenue collection in subsequent years.
