LSA: Everything You Need To Know

LSA: Everything You Need To Know


What is LSA?

LSA, d-lysergic acid amide or ergine, is a product during the creation of LSD, and psychoactive in itself. It was later discovered to be natural, and is known as a chemical in Morning Glory seeds, as well as Ololiuhqui (Rivea corymbosa) & Hawaiian Baby Woodrose (Argyreia nervosa) seeds, some Convolvulaceae vines, and fungi such as Sleepy Grass. Chemically it is known as LA-111, and is an ergoline alkoid.

As a precursor to LSD, the chemical structure of LSA and LSD is similar. Although active in microgram doses, LSA is not as potent as synthesised LSD, and shows a distinct character in its effects.

In the black market, LSA has often been sold as LSD, since it is much easier to obtain. Morning glory is the best known source of LSA, and its effects have been known to the native tribes since ancient times.

While both Hawaiian Baby Woodrose Vine and Morning Glory contain abundant LSA, garden center type seeds of the Morning Glory can be covered in fungicide to prevent mold. Accidental consumption of chemically treated seeds have been reported to cause nasty headaches and a prolonged nausea. Of course, Morning Glory seeds obtained from a reputable source are not treated with toxic products.

LSA Chemistry

Upon analysis, Albert Hoffman found LSA to be very similar to LSD in structure. The main difference being that LSA has NH2, whereas LSD has N(C2H5)2. LSA is largely insoluble in water, but can be dissolved in ethyl alcohol and methyl alcohol.

Jonathan Ott reported large, over ten-fold variations of alkaloid concentration from batch to batch of various LSA seeds. Some other ergoline alkaloids discovered in the seeds were: ergonovine, elymoclavine and lysergol.

"TiHKAL: The Continuation" is a book published by Alexander Shulgin. The work paints a broad picture of tryptamines, and delves into the mental and physiological effects of LSA. Shulgin says that a half milligram dosage (a tiny amount, but large compared to LSD doses) of LSA led to “a tired, dreamy state,” lingering off after around 5 hours. He dismisses its epimer as a major active psychoactive in Morning Glory seeds, citing Albert Hofmann’s self-trial of the substance, in which Hofmann said he got little effect but a feeling of “tiredness and emptiness.”

He writes that the LSA epimer is C-8 inverted, identifying it as either isoergine or d –isolysergamide. Pointing to the fact that lysergic acid and ergine are scheduled in the US, he proposes that it is simply a governing tactic to better enforce the laws surrounding LSD, since they are involved in its synthesis. Shulgin’s book sheds much needed light on the chemistry of LSA & LSD, describing their drug relatives and other tryptamines. However, debates on the similarity between an LSA and LSD trip still continue.


LSA Effects

LSA Effects

Whilst not as powerful as LSD, LSA can induce light to medium strength psychedelic effects that are reminiscent of LSD, although distinctly more sedative and with more physical side effects. LSA produces most of the common effects known from the class of psychedelic substances. Indigenous Mexican tribes used LSA in sacred ceremonies, providing further evidence for their entheogenic value. Effects vary largely from person to person.

The range of POSITIVE EFFECTS includes:

  • Psychedelic headspace
  • Geometrical visions
  • Euphoria
  • Sedation
  • Philosophical introspection
  • Feelings of unity and connectedness

One common and frequent experience is that of nausea, sometimes leading to vomiting. Due to a number of other alkaloids being present in the various types of LSA seeds, a complete toxicity assessment is to available, to our knowledge. There have been reports of LSA containing cyanogenic glycosides, which also occur in certain types of nuts and beans. It has been speculated that LSA doesn‘t cause nausea by itself, but that the accompanying alkaloids are causing it.

In addition to the hallucinogenic effects of LSA, it is not uncommon to experience feelings of drowsiness and sedation. Some have also reported having mixed results session to session, even though ingesting the same amount of seeds from the same batch as their previous trip. This can be related to whether you have eaten anything before you take LSA. It is generally advised that you have an empty stomach before taking LSA.

A standard trip on LSA usually tends to last between 6-10 hours on average, but this is anecdotal and can vary person to person.

Possible Negative Effects:

  • Nausea, vomiting
  • Mental confusion
  • Muscle cramping
  • Increased anxiety
  • LSA can produce a hangover and afterglow that feels somewhat spacey and light headed.Morning Glory

History of LSA

History of LSA

Seeds from tropical liana containing LSA have reportedly been used in Mexico for centuries. It was first documented in the late 16th century by Spanish conquistadors that priests of the indigenous Mexican tribes would consume the seeds in order to communicate with gods. It was reported that upon consumption, the native shamans would enter a delirium and experience divine visions.

The Spanish conquistadors considered the rituals a diabolic blasphemy and attempted to stop its use as well as prevent knowledge from spreading. LSA seeds were rediscovered in 1941, when enthobotanist Richard Schultes reported of their usage dating back to Aztec times. Later, it was reported to be used in ceremonies of the Zapotec Indians.

Samples of Ololiuqui (Turbina corymbosa) seeds have been sent to Albert Hofmann, the creator of LSD, for analysis – he was surprised to find the active compounds to be remarkably similar to LSD. First self-experiments are reported to have made him feel tired and put him in a dream like state.



Seeds containing LSA, such as Morning Glory, are not illegal. However, the production, extraction and consumption of LSA is illegal in many countries around the world. For example, LSA is considered a controlled substance in the Netherlands, a Class A drug in the UK and a schedule III drug in the USA.

Countries that do not currently have a classification for LSA or enforce any law include Canada and Hungary.

Drug Testing

LSA is not looked for specifically in most standard and extended drug tests. However, due to its chemical structure and nature, it has the potential to possibly trigger an alert on tests looking for LSD.

LSD vs. LSA - The Difference


  • There are no known fatalities associated with LSA. There is, however, a risk of overdosing. Those who are impatient or take too much can end up in a long, extremely unpleasant trip. One such prolonged and difficult experience was brought on by double dosing when the initial amount didn’t seem to be doing much. It ended up lasting 36 hours – with physical discomfort lasting even longer. Physical side effects can be sensitivity to light, headaches and tired limbs.

  • LSA can take quite a while to kick in, so be patient. Do not overdose, and run the risk of a bad trip. As always, start out with low doses and get to know your batch.

  • Do not take if you are pregnant or breast-feeding and do not combine LSA with other drugs, medicines or alcohol. It is highly advised you do not take LSA if you have high blood pressure, heart disease or are prone to panic attacks.

  • Make sure you take it in a safe environment with someone you trust to watch over you. Do not attempt to drive or operate machinery under the influence.

  • Keep LSA out of reach of children.
