I understand there is much misinformation and romanticising of cultures foreign to us. Similar things are done for instance to Indigenous Americans, both North and South. So, if you've had no direct contact with said people, how are you to know any better.

But having spent a little time talking with indigenous Australians, I know what a hot topic it is. Foreigners (Europeans) invaded their lands, forceably and unintentionally through disease wiped out large portions of their population. Then those who survived were removed from their lands, people, families, culture and language. You then get the more foreigners making up fanciful interpretations of the shreds left of their culture, naturally they're quite upset.

Further on the topic of the Pituri, everything I have thus read on the topic indicates that the active chemical substance is a nicotine compound. So, if ever you've smoked tobacco yourself, other than a bit of light-headedness, it has no psychoactive properties. It appears that from all available European records it was used as stimulant to help them with strenuous activities, such as long treks through the bush or desert. It is to be noted, that the particular tribes who engaged in its use were wiped out and there is no known surviving cultural knowledge. Further, as I pointed out in my previous comment, such knowledge of Pituri was for the privileged few (initiated), most notably old men. Europeans while they did note the use and effects of the plant, did not bother to ask what it meant for Aboriginal people, whether there was any sacred or spiritual aspect to it's use. So anything that you read today about their use of it is pure speculation or pure fantasy.

This quite detailed article on the topic is a tantalising glimpse of its use.

The previous link I provided, also gives a first hand perspective on the general indigenous attitudes towards traditional cultural use of psychedelics. It is to be noted, that there is a dearth of information of such use by these people, either because it was sacred and closely guarded secret that died out with the people, or as the commentator of the above link puts it, their ceremonies were "family orientated" affairs, where rhythmic dancing and singing was used to induce trance like states.

An excellent research resource of all things chemical and plant based that affect human consciousness can be found at Erowid.org.

I hope you understand, my intent is to inform and not attack you. I still love your creativity and work.
