When it comes to psychedelics, there are a lot of questions about what’s safe and what’s not. One big question is: Does LSD expire? In this blog post, we’ll explore that question and see whether it’s safe to consume expired LSD. Read on!

TL;DR

  • Technically, LSD may expire and/or lose it’s potency. ✔️
  • If you store LSD well, it can last for years! ✔️
  • If you suspect your acid has “expired,” you may be risking a bad or weak trip. ⚠️

Does LSD Expire?

Does LSD Expire

Lysergic acid diethylamide is a potent psychedelic drug that can produce powerful visual hallucinations and profound changes in consciousness. The effects of LSD are long-lasting, usually lasting for 12 hours or more. Because LSD is so potent, it’s important to know that it doesn’t go bad like other drugs. In fact, LSD can be stored for years without losing its potency. That is especially true if you preserve them well. However, LSD can become less potent if it’s exposed to direct sunlight, humidity or heat. 

So, does LSD expire? In a way, it does. However, it is hard to predict exactly when it will expire, like with food. Tabs, microdots, liquid or sugar cubes LSD all have different properties. And sometimes users find that their shelf lives differ a lot. When does LSD expire? Let’s explore LSD shelf life!

Potency of Liquid LSD

The potency of LSD depends on how it is stored. Liquid LSD stored in a glass container in the freezer may remain potent for up to 2 years. However, if it is stored in a dropper at room temperature, or even in the fridge, it will only remain potent for a few days (usually about a week).

Potency of Sugar Cubes LSD

Sugar cubes are a popular method of ingestion for LSD. When stored in a dry environment at room temperature, a sugar cube can maintain its potency for up to 10 weeks. However, if the sugar cube is exposed to humidity or light, the LSD will degrade much quicker. The best way to store sugar cubes containing LSD is in an airtight container in the freezer, where they can retain their potency for up to 3 years. 

Potency of Blotter Paper

Blotter paper, also known as LSD blotter, is a sheet of absorbent paper that has been impregnated with LSD, typically by soaking the paper in an LSD solution. Microdots are similar to blotter paper, but contain much smaller doses of LSD. Blotter paper and microdots are typically stored in a fridge to prolong their potency. However, they will usually go bad after six weeks. If stored in a freezer, wrapped in tin foil and placed in a plastic bag, they can last for up to three years.

What Makes Acid Expire?

What Makes Acid Expire

Does LSD expire? We already know it does! But why, exactly? Here is what makes acid go bad, and tips on how to prevent it!

Light 

LSD is known to be light sensitive and will decompose when exposed to direct sunlight or fluorescent light. This means that if you’re storing your LSD tabs in a clear container, they should be kept away from direct sunlight or fluorescent lights, otherwise they may not last as long as they should. 

Humidity 

LSD is also sensitive to humidity levels. When stored in high humidity levels (around 70%) for an extended period of time, the potency of the drug will decline over time. This means that if you’re storing your LSD tabs in a humid environment, make sure to keep an eye on them and move them before too much potency has been lost.

High Temperatures 

High temperatures can also affect the potency of LSD. If you’re storing your tabs at room temperature or higher – even just above freezing – they may not last as long as they should, due to accelerated decomposition rates. It’s best to store them in a cool and dry place so that their potency isn’t affected by heat or humidity levels.  

Air   

Exposure to air can also cause the decomposition of LSD over time. Oxygen exposure breaks down molecules over time, which affects the efficacy of drugs like LSD and MDMA when stored for extended periods of time. To avoid this issue, make sure your LSD tabs are properly sealed and stored away from oxygen-rich environments, such as near open windows or other sources of air circulation.

Potential Dangers of Taking LSD That Went Bad

When it comes to taking drugs, especially psychedelics like LSD, safety is key. While most people know that taking expired LSD won’t be as potent as fresh acid, there is still a lot of confusion and uncertainty around the potential dangers of taking expired LSD. In general, taking a dose of LSD that has “expired” shouldn’t affect your physical health (except for the psychedelic effects, of course). However, there are some other related risks.

The main danger of taking expired LSD is that you may not get the same effects as you would with fresh acid. This could lead to an unpleasant experience or worse – a potentially dangerous situation if you are not prepared for unexpected effects. A bad trip may cause nausea, gastrointestinal issues, and anxiety.

Editor’s Note

A friend of mine used “expired” acid for microdosing. He said: “It’s a win-win situation. If it’s still potent, I’m getting a small treat; and if it’s not, I’m happy I didn’t just throw it away.” Honestly? I think it’s an amazing attitude.

Additionally, due to its potency levels decreasing over time, it can be difficult to gauge when exactly the acid will go bad, so you may be risking taking a fully potent dose without knowing it. So, if you want to take expired acid for a weaker psychedelic experience, it’s best to take a smaller dose, or wait a few weeks or months more.

Although there have been no documented cases of anyone having adverse side effects after taking expired LSD, it is important to keep in mind that even minimal effects can cause you to behave differently than normal and endanger yourself or others around you. Therefore, it’s important to always be aware of your surroundings while under the influence so that you don’t put yourself at risk unnecessarily.
