How to Store LSD (A Full Guide)

How to store LSD

LSD is a delicate compound that requires care. When LSD is not correctly stored, its potency lowers, making dosing tricky. Without knowing how potent degraded LSD is, it can be tempting to take too much when it doesn’t work as anticipated or is assumed to be less powerful. LSD testing kits cannot show potency or if LSD has degraded, making proper storage essential. However, LSD can still be kept for long time periods if the appropriate measures are taken by understanding what environmental factors need to be controlled.

TL:DR: Critical Factors for Proper LSD Storage

The safest, most common way to store an LSD blotter over the long term is to wrap it in tinfoil, put it inside an airtight container, and stored it in a freezer. Liquid LSD is also best kept in an airtight, opaque container in the fridge or freezer.

Thumb Rules for Proper LSD Storage

  • Dark - Sunlight destroys LSD
  • Cold - LSD is stable in cold environments
  • Dry - Moisture contributes to LSD degradation
  • Airtight - Oxygen breaks down LSD

What is LSD?

LSD chemical structure

LSD stands for lysergic acid diethylamide; a synthetic compound derived from ergot fungus discovered by chemist Albert Hofmann. LSD is one of the most potent psychedelic substances and is effective in tiny doses measured in micrograms.

Also known as “acid,” the compound is typically found on blotter paper with colorful artwork, as a liquid, or in less common forms like gummies, sugar cubes, and microdots. The current resurgence of psychedelic research has found evidence LSD may help treat mental health conditions like depression or addiction.

Why Does LSD Degrade?

Types of Tolerance to Drugs

When LSD is produced, its final form is salt and is stable in water and the cold. However, LSD is easily damaged by heat, light, and oxygen.

Alexander Shulgin, the prolific chemist who rediscovered MDMA, notes LSD is “unusually fragile.” In his book Thikal, Shulgin explains that there are two weak points in the chemical structure of LSD.

  • One point is scrambled by high ph conditions, turning it into the inactive iso-LSD.
  • The second weak point is a site particularly affected by water and alcohol in combination with sunlight which turns LSD into lumi-LSD, which is also inactive.

Shulgin also carefully notes that tap water can degrade LSD because of chlorine added.

Controlling these for these conditions is simple. A 1998 paper analyzing the storage of LSD in urine samples for people’s drug tests outlined some of the specifics:

What Temperature Degrades LSD?

Cooler is better has been established by the 1998 paper listed above. If LSD isn’t going to be used in a few weeks, it should be put into long-term storage. Unfortunately, not much testing has been done for the exact threshold for heat, but here is what we know about temperature.

  • At 25 degrees celsius, the loss of LSD concentrations was less than 15%. However, after four weeks, there was a reported 30% loss in concentrations of LSD
  • At 37 degrees celsius, researchers reported a loss of 40% in LSD concentration

Effects of Humidity and Oxygen on LSD

Oxygen is a very reactive element and breaks down LSD through oxidization. LSD is water-soluble and is not harmed when dissolved in water. However, LSD in water will degrade quicker than properly stored blotter because water contains some oxygen.

  • Keeping LSD inside an airtight container in a deep freeze is the best protection from moisture and oxygen
  • Blotter is often distributed wrapped in tinfoil, but this is not an ideal airtight container. LSD in tinfoil should still be ideally in a cool, dry place for no more than a few weeks
  • Silica packets, like those found in vitamin bottles, can be recycled and added to a storage container to keep a humid environment dry

How Light Effects LSD

Sunlight degrades LSD rapidly has been proven by the 1998 toxicology paper. Even inside an opaque plastic bottle or the typical amber dropper, LSD can degrade in direct sunlight.

  • An ideal container blocks all UV light. Blotter should be at least wrapped in tinfoil and placed inside an opaque container or amber vial if liquid
  • If liquid LSD is kept in a clear bottle, with high exposure to UV light, after only 8 hours, LSD can degrade by more than 50%
  • Fluorescent light degrades LSD, although far less rapidly. Stored in a transparent vessel under fluorescent light, LSD will likely degrade around 10% over a two week period

Nasal Spray Vs. Infusion Ketamine: Which is Better?

Whether LSD is on blotter paper, in liquid, sugar cubes, or microdots; oxygen, temperature, humidity, and light must be controlled to preserve the shelf life of LSD.

How to Store LSD Blotter

Keeping blotter safe and potent is best done wrapped in tinfoil, placed inside an airtight plastic container, and kept in a freezer.

Technically, blotter can degrade at room temperature over time, although anecdotes from people eating acid found from the 60s suggest a freezer may not be necessary.

When taking blotter in a container from a freezer, be aware that condensation can form on the container's lid.

How to Store Liquid LSD

Liquid is prized for ease of dosing; however, it can evaporate if not in an airtight environment.

Any container should be opaque or amber glass to protect from light.

Liquid LSD is often diluted, however, using tap water can destroy LSD because of chlorine added. Very little chlorine is needed to break up the tiny amount of LSD in a solution. For this reason, only distilled water or high-proof alcohol should be used to dilute.

Stored inside an airtight container in the freezer is ideal for liquid LSD but choosing a vessel that will not break is necessary.

High-proof alcohol is good for storage as it can be safe, but still liquid. However, keep in mind that deep freezes can get cold enough to freeze even 80 proof alcohol.

How to Store LSD Sugar Cubes

Liquid LSD was commonly added to sugar cubes in the 60s and 70s.

Because sugar is a desiccant, meaning it attracts water molecules and keeps the LSD dry, sugar cubes are a pretty good storage method.

Over the long term, sugar cubes should still be kept in airtight containers as best practice.

How to Store LSD Microdots

Microdots were popular in the 60s and have not been common for some time. However, with the resurgence in interest in psychedelics, microdots have been spotted in some grey market online dispensaries.

Microdots are typically very potent and should be stored in the same environment as blotter.

Does LSD Go Bad?

LSD degradation means it will become less potent if not stored correctly, not dangerous. Depending on the length and type of exposure, LSD will still have psychoactive effects as it does not immediately break down; the process in many situations is gradual.

As Shulgin states in Thikal, reactions degrading LSD create compounds called iso-LSD and lumi-LSD, which are both biologically inactive in humans. Even LSD from the 60s, if stored correctly, could theoretically be effective, and if degraded, there is no reason to believe it is somehow “bad acid” or toxic.

The Bad Acid Myth and How to Test LSD

The only “bad acid” is not actually LSD. According to the TripSafe organization, testing LSD for purity is a safety concern because of a toxic drug in circulation 25i-NBOMe. This substance can cause hallucinations like LSD and be absorbed into blotter paper.

The gold standard of testing for the presence of LSD is the Ehrlich Test. Other tests like the Marquis or Mecke can help determine if other substances like opiates or MDMA, but are not proven to be reliable when testing for LSD alone. The Ehrlich Test tests for “indoles,” a class of drugs of which LSD is a part.

The Elrich test is simple, after taking only a small piece of blotter or candy several drops of the Ehrlich test solution are dropped over the LSD. After a few minutes, the color of the solution should turn purple, proving the LSD is real. If not purple, further testing with other kits is possible to determine what the drug is. However, if it is not possible to test the LSD, it can be assumed to be 25i-NBOMe and dangerous.

Safely Using LSD

Microdosing and Creativity

LSD is not considered a toxic substance, requiring a massive amount to become dangerous. The real danger of LSD lies in taking large doses that could be psychologically harmful or cause people to put themselves in unsafe situations. Because of this risk, proper storage of LSD is part of safely interacting with this chemical - without knowing the potency of a drug, dosing correctly becomes trial and error and, therefore, risky.

Storing tested LSD in a cool, dark, dry, and airtight space is of utmost importance. Tinfoil and plastic bags can protect from air, light, and moisture. However, a temperature-controlled environment with zero air flow is ideal to ensure LSD maintains its potency and is used safely.
