1s-LSD is one of the newest LSD derivatives and is currently offered as a legal alternative to classic LSD. The substance has quickly attracted a lot of attention because it shares similar properties with LSD but is not regulated under the Narcotics Act. As a result, 1s-LSD is currently freely available on the market and is sold as blotters in various online shops. In this article, we provide an overview of its effects, dosage, user experiences, and the current legal situation.

What is 1s-LSD?

Origin and Development of LSD Derivatives

1s-LSD is a synthetic LSD derivative. Such substances are specifically developed to mimic the known properties of LSD while not being directly covered by the Narcotics Act (BtMG).

In recent years, there have been several of these variants:

  • 1P-LSD – one of the first legal alternatives, now banned
  • 1V-LSD – followed shortly after, also now prohibited
  • 1cP-LSD – also banned after it became popular
  • 1D-LSD – was offered as the next legal variant, now banned
  • 1s-LSD – considered the latest in this series and has quickly gained significance due to its legal availability

Differences Between 1s-LSD and Classic LSD

Chemically, 1s-LSD, like its predecessors, is based on the structure of lysergic acid diethylamide (LSD), but features minor modifications. These changes ensure that it is not automatically classified as classic LSD under the law.

For users, this means:

  • Availability: 1s-LSD is legally available online, LSD is not.
  • Form: Both substances are usually offered as blotters.
  • Effects: User reports describe very similar effects, sometimes slightly weaker or shorter in duration.

Why 1s-LSD is Considered “Legal LSD”

The term “legal LSD” comes from the fact that 1s-LSD is currently not explicitly listed in the BtMG or the New Psychoactive Substances Act (NpSG). This means it can be legally sold and purchased in Germany. Vendors usually label it as a “research chemical” or “not for human consumption,” but legally it is freely available.

Many users therefore see 1s-LSD as a legal alternative to LSD, with comparable use and effects, but without the status of a prohibited substance.

Comparison: LSD vs. 1s-LSD

Characteristic LSD (classic) 1s-LSD (derivative)
Legal status Prohibited (BtMG) Legal, not listed in BtMG/NpSG
Form Blotter, rarely liquid Blotter, available online
effects Strong, long-lasting Very similar, sometimes milder
Availability Illegal Can be ordered from online shops

 

What are the effects of 1s-LSD?

Typical effects compared to LSD

Many users describe the effects of 1s-LSD as very similar to classic LSD. Typical effects include altered perception, visual patterns, more intense colors, and a changed sense of time. Some users also report increased creativity and heightened emotional experiences. Compared to LSD, the effects of 1s-LSD are sometimes considered somewhat milder or shorter in duration.

User experiences

Reports from the community show a wide range of experiences. Many users describe positive experiences, including heightened sensory impressions, intense thought processes, and a sense of connectedness. Others note that the effects are subtler than with LSD and are often perceived as pleasantly clear. The intensity of the effects often depends on the dosage and individual perception.

Duration and intensity of effects

The effects of 1s-LSD usually begin within 30 to 90 minutes after ingestion. The main effects typically last between 6 and 10 hours, while aftereffects can be felt for longer. Many users report that, compared to LSD, 1s-LSD has a somewhat shorter overall duration and lower intensity, but the effects are generally comparable.

Aspect LSD 1s-LSD
Perception Very intense, strong visual effects Similar, sometimes a bit milder
Emotional effects Strongly enhanced Comparable, often described as clearer
Duration 8–12 hours 6–10 hours
Aftereffects Longer lasting Shorter, usually moderate

How is 1s-LSD dosed?

Microdosing with 1s-LSD

Many users take 1s-LSD for microdosing. This involves taking very small amounts that do not trigger hallucinogenic effects, but are intended to support concentration, creativity, or mood. Typical dosages are about one-tenth to one-twentieth of a blotter.

Dosages for a Full Experience

According to user reports, a full psychedelic experience typically involves taking half to a whole blotter. Some users mention higher amounts, depending on their tolerance and the desired intensity. Since there are no official guidelines, these recommendations are based solely on community reports.

Differences Depending on Individual Perception

The effects of 1s-LSD can vary from person to person. Factors such as body weight, previous experience with psychedelics, set and setting, and individual sensitivity all influence the intensity. As a result, reports on the ideal dosage differ widely.

Dosage Form Typical Amount Effects
Microdosing 1/10 – 1/20 blotter Subtle effects, increased clarity
Moderate Experience 1/2 blotter Mild to moderate psychedelic effects
Full Experience 1 blotter or more Pronounced visual and emotional effects

 

What Experiences Are There with 1s-LSD?

Positive Feedback from the Community

User reports generally describe 1s-LSD in a positive light. Many users mention clear visual effects, enhanced colors and patterns, and a deeper sense of self-awareness. Creative thinking and new perspectives on everyday topics are also frequently reported. Some users highlight that they feel less loss of control with 1s-LSD and find the experience easier to manage. For this reason, some consider the substance more pleasant and accessible than classic LSD.

Comparison to Other LSD Derivatives

When directly compared to 1P-LSD, 1V-LSD, or 1D-LSD, many users report that 1s-LSD produces almost no differences in effects. Some describe it as slightly milder or shorter in duration, while others find it nearly identical. 1s-LSD is most often compared to 1V-LSD, which was also legally available for a time. Users see 1s-LSD as a natural successor to these variants, behaving similarly in practice and use.

Why Experiences May Vary

The wide range of user reports shows that the effects of 1s-LSD are highly individual. Differences arise from factors such as dosage, body weight, current state, and the environment during use. Personal expectations and previous experience with psychedelics also influence how the substance is perceived. As a result, experiences range from very subtle, clear effects to intense trips similar to classic LSD experiences.

Buying 1s-LSD – How Does It Work?

In which shops is 1s-LSD available?

1s-LSD is offered in various online shops that specialize in research chemicals and legal alternatives. These shops usually present it as a product for research and analysis, even though many people use it as an LSD substitute in practice. Since it is currently not listed in the BtMG, it can be ordered freely.

Typical forms of sale (blotters, units)

The most common form is blotters, which are small pieces of paper soaked with the substance. Standardized amounts are usually offered, for example, 100 µg per blotter. Many shops sell single units, packs of 5 or 10, and sometimes larger quantities for regular customers.

What customers should look for when buying

Anyone ordering 1s-LSD online usually pays attention to the seriousness and reliability of the shop. Transparent product information, secure payment options, and discreet shipping are important. Since the market is growing rapidly, it is worth checking customer reviews or experiences to find trustworthy providers. Some shops explicitly state that the products are “not for human consumption,” a legally standard disclaimer that does not restrict sales.

Is 1s-LSD legal?

Legal situation in Germany

Classic LSD is clearly prohibited in Germany under the Narcotics Act (BtMG). Production, possession, and trade are punishable offenses. The situation is different for 1s-LSD: The substance is not currently mentioned in the law and therefore does not automatically fall under the BtMG.

Distinction from the BtMG and NpSG

Many LSD derivatives have been banned in the past under the New Psychoactive Substances Act (NpSG). This includes substances such as 1P-LSD, 1cP-LSD, or 1V-LSD. 1s-LSD is not currently listed. This creates a legal loophole that allows vendors to offer the substance.

Why 1s-LSD is currently freely available

Since 1s-LSD is not mentioned in either the BtMG or the NpSG, it is currently considered legal. Shops usually label the blotters as “research chemical” or “not for human consumption” to be legally protected. For buyers, this means that 1s-LSD can currently be ordered freely, although the legal situation may change in the future.

Can 1s-LSD be detected in a drug test?

Will a standard drug test detect 1s-LSD?

The common rapid tests used during traffic stops or in the workplace are designed to detect the most well-known substances. These include cannabis, cocaine, amphetamines, opiates, and classic LSD. Since 1s-LSD is chemically slightly modified, it usually goes undetected by these standard procedures. If you are only tested with a regular urine test, you are unlikely to get a positive result for 1s-LSD.

Can a laboratory detect 1s-LSD?

The situation is different in specialized laboratories. With modern methods such as gas chromatography-mass spectrometry (GC-MS) or liquid chromatography (LC-MS/MS), it is possible to identify metabolites of 1s-LSD. However, these analyses are complex, expensive, and are typically only used when there is a specific suspicion.

Routine checks or rapid tests do not detect 1s-LSD, but targeted laboratory analyses could identify the substance.

What does this mean for your driver’s license and job?

Even though 1s-LSD rarely shows up in tests, this does not mean it is risk-free in everyday life. If you drive under the influence of a psychoactive substance, you can face legal problems—even if the specific substance is not detected. The same applies at work, especially in safety-critical professions.

How long will 1s-LSD remain legal?

Examples of earlier LSD derivatives (1P-, 1V-LSD)

In recent years, several LSD derivatives have appeared on the market that were initially freely available. These include 1P-LSD, 1cP-LSD, 1V-LSD, and also 1D-LSD. All of these variants were initially promoted as legal alternatives and quickly gained popularity. After a certain period, however, they were added to the New Psychoactive Substances Act (NpSG) and thus banned.

The pattern is clear: As soon as a new derivative receives greater attention, authorities usually intervene after a few months or years. 1s-LSD therefore joins a series of substances that were initially legally available but whose status was later changed.

Discussions about possible changes

There is already discussion among experts and in the media about whether 1s-LSD will soon be covered by the NpSG. The more the substance is used and the more it is noticed by the public, the greater the likelihood that it will be included in legislation. Especially when authorities increasingly hear about use or misuse, the pressure to close legal loopholes rises.

Current outlook

Currently, 1s-LSD is legal and freely available in online shops. Buyers can purchase it without legal risk as long as it is not listed in the BtMG or NpSG. However, it is unclear how long this status will remain. Developments with other LSD derivatives suggest that a legal change is likely.

For consumers, this means: At the moment, 1s-LSD is an available alternative to LSD that exists in a legal gray area. However, it is important to keep in mind that the situation can change at any time if lawmakers take action. Whether this happens in the short term or only after several years depends mainly on how much attention 1s-LSD receives from the public and authorities.

Conclusion

Currently, 1s-LSD is the most advanced variant among LSD derivatives and is offered as a legal alternative to classic LSD. It joins the ranks of substances such as 1P-, 1V-, or 1D-LSD, which were previously available for a period of time.

In terms of effects and use, users report many similarities to LSD. Experiences range from more subtle effects to trips that are almost indistinguishable from LSD. This makes 1s-LSD very similar to the well-known derivatives.

The crucial point is the legal status: Since 1s-LSD is not listed in the BtMG or NpSG, it is currently legal to order. How long this situation will last is uncertain—at present, however, it offers an available and legal option for anyone interested in LSD derivatives.
