In 1965, the first report was published in a scientific journal on the isolation of the alkaloids nemate and demate from the species Actia maidani, shortly after that the isolation of demate from the species Actia flavophylla - both Australian species - was reported.

During the next decade, a number of other journals followed and reported the findings of these alkaloids in additional species from Africa, Asia and Oceania. These reports came at a time when Western history saw a great increase in public curiosity about psychedelic substances, which nevertheless remained as obscure footnotes in the phytochemical literature for more than - 20 years.

This may be due to the fact that Demet was an obscure and unpopular psychedelic mediator, at least until the late 1980s.

Several publications that appeared in the early 1990s raised awareness of this fact. The first was a scientific text (Collins, 1990) followed by popular books more specifically about plants and psychoactive substances (Ott, 1993).

Around the same time several students from Australian universities came across this information in scientific journals.

In 1992, one of the anonymous researchers from Australia, published a report on successful experiments in extracting and smoking the alkaloids from the stem barks of Acacia Maidani. The researcher first tried to smoke the bark itself, which in turn had very mild effects.

At the beginning of 1993, one researcher published a report on the forum, in which he details the first documentation of the use of a decoction of leaves from Acacia flavophila, while under the influence of the seeds of a white saffron he had eaten before. Later that year, another unknown person consumed the same combination and posted it on the forum. These reports quickly multiplied on the forums different as the Internet grew and developed in the 90s.

As of this time, experiments with what became known as analogues of Aya (a combination of plants that are not traditional, but contain the same alkaloids) were in their infancy.

In the same year in the USA, a small number of people experimented with the root of the plant Desmentos and the leaves of Phalaris (digger) in combination with the seeds of the White Shaver, this information was not clear until the moment when Jonathan Ott published his book "Analogues of Ivosca" (1994).

During the 1990s, a period of intensive investigation into the psychoactive properties of various acacia trees emerged, not by academics, but by amateur psychonauts in many parts of the world, especially in Australia.

Initially, much of the focus was on A. phlebophila—it has fairly reliable demate content, with few, if any, additional alkaloids.

They then focused on A. maydani which has been shown to be a less stable source of demat due to genetic variation within the subspecies and in nemat content more often than demat.

This limited focus quickly led to some negative effects on both species in the wild.

- Acacia flavophylla grows on Mount Buffalo in the state of Victoria, Australia.

This plant population suffered from both overharvesting and damage caused by the rust fungus, which adversely affected the health of this variety in the late 1990s (Heinze, 1998). Since then, the giant fire at Buffalo Mountain seems to have destroyed the infected material and today the species is regenerating well.

- Action Meydani suffered partially due to ignorance created following a detailed article on the extraction of alkaloids from the stem, published in 1965 (Fitzgerald & Siomis).

Following this article many people assumed that this was the only part of the plant that required extraction. Wild and cultivated plants were roughly stripped and many trees were killed because of this approach, not all trees were even properly identified.

To this day, similar cases continue to occur, they are documented and discussed in cultivation and use forums around the web. Those who bought these extracts were apparently unaware of the ecological destruction that may be associated with their production.

Due to these issues, some of the underground researchers in Australia decided to start sharing with people some of the information they learned about acacias. These researchers hoped to encourage others to learn sustainable harvesting techniques, to shun the commercial trade in acacia alkaloids and to research a variety of other species to reduce the pressure on threatened species such as Acacia flavophila.

Method of investigation and use:

Amateur researchers studied species for which chemical analysis had not been published before and species that were reported as positive but were not further tested. Some approached this by performing extraction (a\b,stb) or paper chromatography.

Some have learned to narrow down the field of identification by taste-chewing a small sample from the plant and comparing it to samples known to be positive.

Another method used is the smoke test - burning a dried leaf and smelling the smoke following indole aromas associated with the presence of tryptamines.

Some researchers believe in their spiritual connection to plants, they choose species to test based on intuitive feelings.

These researchers were motivated by a lack of access to laboratory equipment used to identify alkaloids with a high degree of certainty. As a result, a large part of these early findings were subjective guesswork following automatic operations and an inability to verify the type of alkaloid.

Through all these approaches, people working in this gray area have increased their amount of knowledge in the field of action alkaloids, at a time when such work has almost disappeared from the academic mainstream.

The risks involved were not only legal/legal, they also included the dangers inherent in human consumption of plants or extracts with known or unknown chemical content.

Aktion's extracts are smoked clean in a glass pipe or mixed with other plants that can be smoked in a pipe/bang/joint - the same way demet has been used for the past 50 years.

Since the 1960s, Mars demats from the solvent directly onto a vegetable carrier (usually parsley).

Since the early 2000s, a mixture of smoking plants with added kaapi (mao inhibitor) has become a popular and accepted means of consumption called Changa.

The addition of the kaapi leaves increases the efficiency and makes it easier to inhale an effective dose. Sometimes, bozin leaves are added to the mixture - which makes the smoke milder and easier to hold in the lungs.

A wide variety of plants can be added to change the taste and effects (Palmer, 2015).

Different plant mixtures emerge from other parts of the world, they use different source plants that are not action plants, such as mimosa hostilis.

Drinking action infusions or alkaloidal extracts in combination with common mao inhibitors (white fraction, kaapi, passionflower) are much less common than smoking, but occur in Australia (Ott, 1993).

Acacia flavophylla and Acacia abatosifolia have been known for their decoction use since 1993, A. maidani since the mid-1990s, A. acuminta since the beginning of 2000. In recent years, Acacia floribunda and other species have been used occasionally.

+Aya ceremonies held today in small groups in Australia often use actions containing demate or the alkaloidal extract instead of using more traditional plants such as psychotrea.

Not all species contain demate and many of them contain substances that are not tryptamines and are unknown.

They may be toxic or dangerous when combined with maoi
