Prohibited in competition
WADA 2026: S6.B, specified, prohibited in competition. The future 2027 List retains this classification. [1] [2]
2026 and 2027 List, S6.B, printed pp.15–16; introductory definitions p.3 · 2026 rules apply from 1 January 2026. Any 2027 material below concerns future rules from 1 January 2027; it is not current clearance.
Isomer distinction
The List places d-methamphetamine in S6.A and levmetamfetamine in S6.B. Both are prohibited in competition; their specified classifications differ. Optical-isomer coverage must not be turned into automatic sanction advice. [1] [2]
Nasal-product exposure
A US DailyMed OTC inhaler label identifies levmetamfetamine as a nasal decongestant for temporary congestion. It warns about local irritation and recurrent or worsening congestion with prolonged use. OTC presentation does not supply a WADA exception. [3]
- The product label is not a dosing guide for sport.
What remains uncertain
- Educational synthesis only; not individualized medical advice, a TUE decision or a sanction prediction.
