I think salvinorin A is stable while it is inside trichomes, or deep within a leaf as an extract, or as salvinorin A crystals. But once it is in molecular form, it is easily degraded by light (tinctures, for example) or maybe oxygen and substances like alkalis and esterase enzymes in solution or thin films.

How stable is your complexed salvinorin, Loveall?  Have you done any stability tests?
