Arkansas (AR) — What’s Legal

Checked Oct 13 2025 • Parent-friendly summary (not legal advice).

Tianeptine: Schedule II — listed under Arkansas controlled-substance regulations.
Phenibut: No state scheduling found (as of 2025). Not a lawful dietary ingredient per FDA.
Kratom (mitragynine / 7-OH): Illegal (Schedule I). Arkansas Schedule I lists kratom’s alkaloids; possession, sale, or use is illegal. A 2025 bill (SB 534) would remove kratom from Schedule I and create a Kratom Consumer Protection Act — not yet enacted.
Nitrous oxide / amyl nitrite (“poppers”): Illegal with intent for intoxication (AR Code § 5-64-1201); violation is a Class A misdemeanor.
THC / Cannabis / Hemp THC: No clear statewide update located; verify current medical/adult-use statutes before publication.
Salvia divinorum / Salvinorin A: No confirmed statutory ban found (as of 2025).
Amanita muscaria / muscimol: No explicit scheduling found; appears legal absent catch-all hallucinogen clauses.
“Mad honey” (grayanotoxins): No AR-specific ban found; treated under general food safety/adulteration laws.

Parent tip: Arkansas still bans kratom and “gas-station opioids.” Avoid unlabeled capsules or shots advertised for “mood or focus.” Report suspect sales to local authorities.
