1SB-LSD is a popular term used in online shops; in official documents and forensic literature, the same topic is usually referred to as 1S-LSD . This very derivative is the focus of political and regulatory attention in 2025 – with a clear tendency to close the "LSD derivative loophole" in the New Psychoactive Substances Act (NpSG). Today (September 26, 2025), the Federal Council is meeting, and the committees are recommending that the prohibition regulations for LSD derivatives be tightened to prevent future circumvention . This is not hearsay, but rather document 366/1/25 . Until the minutes of the plenary session are available, the status is still in flux , but the direction is clear.
We map the legal situation , risks and dynamics for you, so that you can make smarter decisions.
Key Takeaways – 1SB-LSD Legality in a Nutshell
- "1SB-LSD" is the official term for 1S-LSD . For legally reliable information, always search for 1S-LSD .
- Germany, September 26, 2025: The Federal Council is discussing the amendment to the New Psychoactive Substances Act (NpSG) . Committees are calling for the description of LSD derivatives to be simplified to prevent circumvention . The decision has not yet been officially communicated. Federal Council
- BMG Line 2025: Amendment to the NpSG for faster, more comprehensive recording of NPS – Goal: Health protection, closing the gaps . BMG
- Austria/Switzerland: Rapid adjustments by decree likely ; situation remains dynamic .
- In practice: Trading/distribution would be clearly illegal if recorded; possession would be assessed differently under the law – details depend on the final version . Customs/import will become riskier.
- Testing & Forensics: With increasing analytical capabilities , detectability increases; "invisible" is a myth.
Why is the question of 1SB-LSD legality in 2025 so critical?
Because Germany is tightening its New Psychoactive Substances Act (NpSG) in 2025 – specifically in the areas where derivative-hopping has been going on for years: new LSD derivative, quickly legalized; regulation follows; next derivative, same game. The Federal Council committees are now clearly stating: LSD alternatives should be covered comprehensively and more simply , instead of adding each individual molecule. This would end the cat-and-mouse game .
At the same time, the Federal Ministry of Health ( BMG ) outlines in its documents on the New Psychoactive Substances Act (NpSG) the direction things are headed: protection against NPS risks , faster response times , and fewer regulatory loopholes . This means that if the Federal Council agrees, the gray area surrounding LSD derivatives will become noticeably smaller .
What is 1SB-LSD (aka 1S-LSD) from a chemical and legal perspective?
Chemically: 1S-LSD is a lysergamide derivative (an LSD relative) with a trimethylsilyl-containing N-acyl side chain . Such N-acyl variants (1P-, 1B-, 1D-, 1V-, 1S-LSD) differ in potency, kinetics, and metabolism – they are not automatically “the same as LSD”.
Legally: It was precisely these structural modifications that previously made it possible to be temporarily excluded from the scope of the New Psychoactive Substances Act (NpSG). This is exactly what the government now wants to eliminate – through a simplified, broader description of LSD derivatives in the NpSG annex , so that subsequent modifications are automatically included. Federal Council
What role does the NpSG play – and why is it crucial?
The NpSG ( New Psychoactive Substances Act) is Germany's instrument against new psychoactive substances (NPS). It specifically prohibits the handling of NPS groups in a traffic-related context (manufacturing, trade, distribution, etc.). An amendment is planned for 2025 that will expand the list/appendix and the system of classification to allow for faster and more comprehensive responses.
In short: Previously there were loopholes ; in the future, a general clause-like approach will be used for LSD derivatives. Less room for interpretation , more legal certainty – and yes, probably less “legal” .
Germany: Is 1SB/1S-LSD legal today?
As of today, September 26, 2025:
- In document 366/1/25 , the committees of the Federal Council explicitly recommend tightening the regulations on LSD derivatives (protection against circumvention).
- The agenda /explanation for item on the amendment to the NpSG states: The description of LSD derivatives in the annex should be simplified and adapted so that circumvention is no longer possible.
- The plenary session is meeting today. Official communication of the decision usually follows promptly; until then, the situation remains uncertain , but: the general direction is in favor of a ban/expansion .
Important: Regardless of how shops blog, the Federal Council/Federal Ministry of Health (BMG) is the authoritative source . Shop blogs are often correct with their predictions, but they are not a legal authority .
Austria: What is the legal situation regarding 1SB/1S LSD?
Austria regulates NPS through a separate NPS regime (in addition to narcotics law) and adapts quickly . Experience shows that derivatives are often added as trends emerge. In practice, this means that rapid regulatory solutions are possible, which is why the legal situation remains volatile . For specific decisions: check official websites (RIS, ministries). (Context: NPS control is intended to be harmonized across the EU, but implemented at the national level .)
Switzerland: What rules apply there?
Switzerland regularly expands its lists of prohibited substances through ordinances ; NPS (New Psychoactive Substances) are proactively addressed. Those who rely on "still legal in country X" often have a short window of opportunity . Check: Narcotics Act/ordinances and the Federal Office of Public Health – updates are posted there. (Principle: monitoring + rapid adaptation .)
How does the legality of 1SB/1S LSD differ from that of 1V, 1D, or 1P LSD?
Historically, individual derivatives were gradually and explicitly included in the regulations (e.g., 1T-LSD 2024). The new course aims to prevent every minor modification from being temporarily legal again. In other words: Those hoping for the "next derivative" will likely see less room for maneuver . More generic coverage equals fewer gaps.
Is a ban on 1SB/1S LSD imminent? What was the outcome of today's Federal Council meeting?
Today, the 1057th plenary session is being held. The preliminary text for the relevant agenda item states: Simplify and adapt the description of LSD derivatives to prevent circumvention . The committee recommendation (366/1/25) moves in the same direction.
- Interpretation: A decision of this kind would drastically change the market immediately (after its announcement/entry into force): distribution would be illegal , and possession would be subject to a different legal framework than trade, depending on the specific design.
- As of press time: The official plenary results have not yet been published. We are working with official documents and explanations – not rumors.
What does this mean in practical terms for buyers, shops and researchers in Germany?
- Buyers/Consumers: Even though possession is traditionally assessed differently than trading/transfer under the New Psychoactive Substances Act (NpSG), new risks arise (e.g., shipping, import, customs, platform blocks). A dynamic of " legal today, not tomorrow " makes returns, warranties, and delivery times problematic.
- Shops: Documentation, COAs , clear legal communication , and possibly a change in product range . Those who continue to sell risk criminal activity .
- Research/Laboratories: There may be special procedures for reference standards and analytics – but here too, the following applies: keep approvals and compliance clean.
How reliable is the detection – do tests play a role?
Standard rapid tests are poor at detecting lysergamides. However, with each forensic publication (metabolites, reference spectra), the probability of detection in specialized laboratories increases. This means that "it won't be detected anyway" is a poor strategy in 2025 – especially if authorities are specifically upgrading their equipment .
EU trends: Will other countries follow suit?
Europe has relied on early warning systems and harmonized measures against NPS for years. If Germany closes the loophole regarding LSD derivatives , it is likely that neighboring countries will follow suit in parallel or shortly thereafter – each using their own procedures . In short: The trend is toward stricter regulations.
What should curious users realistically expect in 2025?
- More clarity , fewer "creative" gaps.
- Faster adjustments , less time to switch to "new" derivatives.
- Stricter platform policies (payments, shipping, ads) will be implemented once an incident has been officially recorded .
- More EAT in Content: Government quotes > Shop hype.
The Federal Council documents and BMG pages are your primary sources – everything else is secondary noise.
Is 1SB-LSD the same as 1S-LSD?
In shop jargon, yes, but in official documents it's called 1S-LSD. For reliable information, always search for "1S-LSD".
Is 1SB/1S LSD legal today?
In Germany: The Federal Council is meeting today to discuss a tightening of the New Psychoactive Substances Act (NpSG); the committees are recommending a broader ban on derivatives. An official plenary decision is still pending. The trend is toward a narrowing of the scope.
What specific changes will the NpSG reform bring?
The system should be formulated in such a way that future LSD modifications are automatically included.
Does this also apply to Austria/Switzerland?
Not automatically – but both react quickly via regulations/lists. Volatile. Check official websites.
1SB-LSD drug tests – visible or not?
Specialized analysis can identify 1S-LSD/metabolites; standard panels are unreliable.
How to validate this today (reality check)
- 1) Federal Council Committee Recommendation 366/1/25 – Wording: “Sharpen the prohibition regulations on LSD derivatives and prevent circumvention” .
- 2) Explanation of the agenda item: “Simplify/adapt the description of LSD derivatives in the NpSG annex” .
- 3) BMG page on the NpSG amendment (Cabinet 02.07.2025) – Goal: faster, more comprehensive regulation.
