Is Endomorphin-1 Legal in West Virginia? (2026)

Rule type

Tier

unscheduled

What the record says

Endomorphin-1 (Tyr-Pro-Trp-Phe-NH2) is not named or scheduled in West Virginia. The state has no chemical analogue statute; only an imitation / counterfeit / misrepresentation offense that turns on appearance or representation, not on a substance's intrinsic structure or effect. Controlling instrument reviewed: None operative - 'Analogue' def (60A-1-101(c)) non-operative; imitation only. Conclusion: no operative instrument reaches a structurally-dissimilar endogenous opioid peptide; status LEGAL at the state controlled-substances level. Residual risk: minimal. Federal floor still applies (Analogue Act human-consumption contingency + FD&C unapproved-new-drug).

Controlling language, verbatim

W. Va. Code 60A-1-101(c): "'Analogue' means a substance that, in relation to a controlled substance, has a substantially similar chemical structure." This definition carries NO general offense; the only operative catch-all is the representation-based imitation-controlled-substance offense. [Definition non-operative; structure prong would fail regardless.]
