Anyone who has ever had an Ayahuasca ceremony knows that it is not "popular at parties." If people were drinking Ayahuasca at parties everyone would be on the floor possibly purging, crying, or overwhelmed in silent joy in the visions they are having. Ayahuasca is not a party drug and no one meets with Mama Ayahuasca to have fun; least of all socialize with other people.
"But two travelers have died after taking part in the ceremony since 2014."
According to the CDC (Center for Disease Control and Prevention) 16,060 people die every year in the US from prescription drugs!
