Which nations have specific laws that allow/ disallow ENTRY of shamanic ritual plants/ herbs such as Ayahuasca? [closed]

Travelling to Latin America to take hallucinogenic drugs: how does one do it safely?

This is a related question, but objective here is different.

I have a few friends from Latin & Eastern European descent that are serious practitioners of Shamanic rituals and healings.

I've been meditating for several years and was curious about participating with them when we meet somewhere (elsewhere in Latin America or SE Asia - outside of their country where they pratice; Mexico & Peru) for a yoga reunion.

Note: I do not even consume alcohol or smoke or have ever thought of indulging in marijuana. But, I am genuinely curious about this.

I am curious about the legality & laws at Point of Entry/ Exit and/ or inside other nations if they carried/ traveled with these/ such plants or their derivatives to our reunion location (still open).

Which nations would be a YES, NO, MAYBE YES, MAYBE NOT to this? I do understand we must err on the side of caution, but I am curious to know if at all Latin & SE Asian nations have "laws" or "practices" around such?

Wouldnt it make sense to have a Wiki of such such type here:
