LEGISLATIVE ARCHIVE. S.751 was signed into law by Governor McMaster on May 18, 2026 as Act R 230, effective immediately. H.5202 remains stagnant in House Judiciary with no legislative action since 2/18/2026; per SC legislative procedure, once one bill in a same-subject pairing is enacted, the companion typically does not advance.

THE FUNDAMENTAL DIFFERENCE
H.5202
NEAR-TOTAL PROHIBITION
S.751
NEAR-TOTAL COMMERCIAL BAN
H.5202 (Teeple, House): Near-total prohibition — unlawful to sell nitrous oxide to anyone except exempt entities. No individual consumer may purchase for any purpose.
S.751 Amended (Sutton/Ott/Zell/S.Garrett/R.Walker, Senate): Near-total commercial ban — unlawful to sell recreational nitrous oxide except to exempt entities. Adults 18+ may purchase only for verified lawful use (medical, culinary with food permit, automotive with dealer agreement, industrial, research, government).
Both bills now impose near-total commercial bans. S.751 preserves narrower exemptions with documentation requirements (food permits, dealer agreements) and is harder to challenge constitutionally. H.5202 takes a broader prohibition approach with simpler exemption categories.

TECHNICAL ISSUES
Chemical nomenclature: S.751 uses “nitrogen monoxide” in its definition — technically that is NO, not N₂O. Both bills include the correct formula N₂O, so legislative intent is clear. H.5202 correctly uses “dinitrogen monoxide.”
Online sales gap: H.5202 has no online sales provisions despite e-commerce being a major distribution channel. S.751 addresses this with third-party age verification and signature-on-delivery requirements.
STRATEGIC ASSESSMENT
S.751 passed the full Senate 42-0 on 3/4/2026 and the full House 116-0 on 5/13/2026; the Senate concurred in the House amendment on 5/14/2026; ratified as R 230 on 5/15/2026; signed by Gov. McMaster on 5/18/2026 as Act R 230, effective immediately. The enacted version is a near-total commercial ban with documentation-based exemptions, online sales provisions, and SLED enforcement — the most comprehensive state-level nitrous oxide regulation in the United States. H.5202 takes a simpler prohibition approach and remains stagnant in House Judiciary since referral on 2/18/2026. Both bills targeted the same outcome; they differ primarily in exemption structure and enforcement mechanisms.
