Many hallucinogens occur naturally, including psilocybin (‘magic mushrooms’), DMT (dimethyltryptamine), Salvia divinorum and mescaline (from the peyote cactus).
Psilocybin or psilocin are hallucinogenic substances found in more than 180 species of mushrooms. They are mainly used for spiritual or recreational purposes and cause similar but distinct hallucinogenic experiences compared with LSD.
It is dangerous to pick and eat wild mushrooms because it is difficult to distinguish edible mushrooms from their poisonous lookalikes. Poisonous mushrooms can cause stomach pains, vomiting and diarrhoea, while some can cause permanent liver damage, respiratory failure, unconsciousness and even death. Symptoms can take up to 40 hours to develop.
DMT is a powerful hallucinogen found in the seeds, bark, leaves or stem of various plants around the world, including some acacia species native to Australia. It is consumed by many individuals as ayahuasca which is mainly used for spiritual purposes. Alternatively, it can be synthesised into a crystalline form which is typically vaporised or smoked.
Salvia divinorum is a species in the mint family which can be chewed, drunk or smoked in order to produce hallucinogenic experiences. Given that salvia is not controlled under the UN conventions, it is classified as a new psychoactive substance.
Mescaline is most commonly known as the active ingredient of the peyote cactus and is used both spiritually and recreationally. The effects of mescaline include visual hallucinations and altered states of consciousness, but can also include vomiting, headaches and fear/anxiety.
Natural hallucinogens and the law
It is illegal to use, possess, supply or manufacture hallucinogens in New South Wales.
How natural hallucinogens are used
Naturally occurring hallucinogens are used in a variety of ways, depending on their form. They are often smoked (with the exception of mushrooms) and can be boiled into tea preparations.
Mushrooms can be dried or boiled, then added to other foods.
Short term effects
The short and long-term effects vary greatly depending on the hallucinogen used. Additionally, the effects of each drug can differ substantially from person to person.
The short-term effects of naturally occurring hallucinogens include (but are not limited to):
- vivid perceptual distortions (hallucinations)
- a distorted sense of time and place
- altered sense of consciousness
- loss of coordination
- increased body temperature and sweating, and/or chills
- nausea and vomiting
The effects produced by these substances, and the user's reaction to these effects, vary greatly between individuals.
Long term effects
Given that these substances both distort reality and alter consciousness, one of the many long-term risks associated with using naturally occurring hallucinogens is a change in personality and/or patterns of thinking.
Other rarer effects include flashbacks (brief but intrusive hallucinogen-like experiences that occur after the effects of the hallucinogen have worn off), hallucinogen persisting perception disorder (HPPD), impaired memory, prolonged depression and anxiety.
Hallucinogens and driving
It is extremely dangerous, as well as illegal, to drive with the distorted sense perceptions, poor coordination and lack of judgement caused by taking hallucinogens.
Hallucinogens and pregnancy
Most of the research looking at hallucinogens and pregnancy have focused on LSD and have provided some evidence that LSD use during pregnancy leads to an increased risk of miscarriage and birth complications. It is very likely that other naturally occurring compounds may have the same effect.
If a mother uses hallucinogens when breastfeeding, it is possible that the drug will be present in her milk and have adverse effects on the baby.
Interaction with other drugs
Cross-tolerance can occur between psychedelics. This means that users with a tolerance to, for example, LSD, may have a tolerance to drugs with similar effects such as mescaline.
Naturally occurring hallucinogens are not thought to cause physical dependence. Regular users may develop psychological dependence, although this is not common.
Given that there is little risk of physical dependence, there are minimal physical effects when use ceases. Users may experience residual psychological effects such as low feelings of anxiety.
Naturally occurring hallucinogens are not particularly toxic drugs; deaths that have been linked to hallucinogens are usually unintended consequences of perceptual distortion, such as falls. Despite this, taking a larger than intended dose can result in extremely distorted perception, unstable mood, intense fear and an extremely depressed mood and can also prolong the experience for much longer than expected.
One of the dangers of using magic mushrooms is that of accidentally ingesting a highly toxic non-hallucinogenic variety. Some other naturally occurring hallucinogens, such as datura, may cause poisoning in high doses.
People who use natural hallucinogens do not generally seek treatment for their drug use and there are few treatment options that can be recommended, apart from those found to be generally effective for drug dependence.
