Going back to calamus, we have alpha-asarone, beta-asarone, and gamma-asarone. Typically beta-asarone is the main oil present at up to 75% of the essential oil. Gamma-asarone is present in very small amounts, like 3.20%, with alpha-asarone being about 1.32%. So gamma-asarone is a very minor player in the oil in most calamus. However, look at this:

So there do exist strains of Calamus in Czech that are high in gamma-asarone. You may want to look into those. Perhaps those are the ones that are the most hallucinogenic and least nauseating. I know for a fact some people get hallucinogenic effects from Calamus. It’s often said that only certain strains are active, and they must be fresh. So maybe gamma-asarone is the main hallucinogen, and it is not stable, so fresh material is needed.

Now if gamma-asarone absorbs well sublingually, and alpha-asarone and beta-asarone do not, then maybe that’s a good way to get the positive effects from it while avoiding the nauseating effects of ha-asarone and beta-asarone.

Definitely more work needs to be done on this.
