well, you're not converting LSA to anything new, if that's what you're wondering.
Cinnamaldehyde is a few steps away from any scheduled compound, and not terribly harmful.
It upregulates mRNA expression of TRPV1, the ion-gated receptor associated with heat and pain; thus, beta-endorphin production occurs as a secondary response.
methinks those people felt some synergistic effects not related to LSA's psychedelic effects, or placebo i.e. they felt what they wanted to feel.
