From Jairo account
Daime is not a drug. It is …
The prohibition of drugs in Alto Santo
Mestre Irineu and Mapacho tobacco
The only other plant substances that alter consciousness that Mestre Irineu specifically promoted was Mapacho tobacco. There is even a famous photo of Mestre Irineu smoking.
Mapacho is a very important plant in the traditional cultures of Ayahuasca-using native tribes.
Mestre would even blow Mapacho smoke over the Daime, a technique from Indigineous Amazonian Shamanism, however he instructed that these shamanic components of the tradition should not be carried on beyond his own lifetime.
