Rep. Trey Caldwell, the lawmaker who helps steer Oklahoma's budget, is pushing colleagues to lock in tax and regulatory rules for a new wave of "heat-not-burn" tobacco products before they ever hit store shelves. His plan would carve out a separate tax category for devices that heat tobacco instead of burning it and order state tax officials to create new excise stamps just for those products. Backers say that kind of early clarity will prevent chaos over how to tax the new gadgets. Critics see something else: the potential for a lower-tax lane for tobacco companies and fresh public-health headaches.
Caldwell, who chairs the House Appropriations and Budget Committee, told the Southwest Ledger that "anything involving revenue and taxation falls within my responsibilities." His official biography lists him as Appropriations and Budget chair at the Oklahoma House of Representatives. He said he wants Oklahoma to avoid the tax fights and confusion that came with the rapid rise of vaping.
Public-health officials and the Tobacco Settlement Endowment Trust have been warning lawmakers that every new nicotine product needs clear tax rules and tight tracking to prevent youth uptake and spotty retail compliance. The TSET board passed a resolution urging legislators to fold heat-not-burn devices into the state's legal definition of tobacco so they can be taxed and regulated the same way as other tobacco products, according to the Tobacco Settlement Endowment Trust.
What SB 680 Would Change And Where It Stands
Senate Bill 680, carried in the House by Caldwell, would amend Oklahoma's cigarette statutes to cover products that are meant to be heated rather than burned and would set a 50% cigarette-stamp rate for those items. The Senate signed off on the bill on March 26, 2025, and it was later engrossed and sent to the House for committee work. Official bill documents state that the Oklahoma Tax Commission would have to issue a new excise stamp just for heated-tobacco products and that the revenue impact is listed as "unknown" because the products are not yet sold in Oklahoma, according to an Oklahoma Legislature fiscal note.
Industry Claims And Independent Research
Tobacco companies argue that heating tobacco instead of burning it cuts measured toxicants. Philip Morris International, for example, points to studies finding that aerosol from its Tobacco Heating System has roughly 90 to 95 percent lower levels of many harmful and potentially harmful constituents compared with cigarette smoke, according to Philip Morris International. Independent reviews and government-funded research tell a more cautious story. Reporting in STAT cites Swedish government-funded work that found residues including tar, nicotine, ammonia and formaldehyde in heated-tobacco aerosol. Public-health groups say that mix of scientific uncertainty and youth appeal is exactly why clear tax and sales rules need to be in place before the products are widely available.
Why It Matters In Oklahoma
Timing is tight at the Capitol. Article V of the Oklahoma Constitution requires lawmakers to adjourn by 5:00 p.m. on the last Friday in May. This year, that is May 29, which leaves a narrow window to move any tax changes, according to the Constitution of Oklahoma. The American Lung Association notes that previous bills that would have created lower tax rates for heated tobacco never became law and the group continues to press legislators to tax all tobacco products at the same rate, arguing that equal tax treatment best protects public health, as outlined by the American Lung Association.
Caldwell's push drops Oklahoma into the same policy conversation as other states trying to decide how to handle heated tobacco, a politically tricky blend of revenue needs, enforcement concerns and public-health risks that is still being sorted out. Advocates on both sides say the coming weeks of House committee work will decide whether Oklahoma creates a new, lower stamp rate for heated tobacco or simply folds the products into existing tobacco rules, a debate tracked regionally by CSG South.
