Chapter 1: What exactly is 1S-LSD?
For several years now, 1S-LSD has been considered one of the last legal alternatives to LSD. Chemically, it is a derivative that is structurally very similar to LSD.
Properties of 1S-LSD
- Not classified as a narcotic (as of now)
- Legally classified as a “research chemical”
- Has effects similar to those of classic LSD derivatives, but is weaker
- Available primarily at smart shops and online stores such as HappyFlower
Significance within the scene
1S-LSD was the last legal alternative to LSD after substances like 1V-LSD and 1D-LSD had already been banned. Many users turned to it as a “bridge” between the legal market and traditional LSD.
Chapter 2: The Road to the Ban
Initial discussions
As early as the spring of 2025, the BfArM’s Expert Committee discussed 1S-LSD. The committee recommended that the active ingredient be added to the schedules of the BtMG.
Committee recommendation
In September 2025, the committee’s recommendation was officially issued: LSD-Kern should be banned.
Federal Council Meeting on September 26
The recommendation was adopted at the Federal Council meeting without much discussion —almost as an afterthought. Yet the consequences are enormous:
- The ban is coming.
- The only thing that remains unclear is when and how it will be implemented.
Chapter 3: What exactly was decided?
The bottom line: The LSD core will be banned.
This means:
- 1S-LSD will be subject to the Controlled Substances Act in the future.
- Trading and selling will become a criminal offense.
- Under the current interpretation, possession will also be a criminal offense once the law takes effect.
Chapter 4: The Legislative Process
Variations of the method
It remains to be seen whether:
- A simple change to the system is made → The ban could take effect immediately
- or a more complex legislative process → would take weeks or even months
Speed
Since this is likely just a change to the facility, the ban can be published at any time.
Next meeting
The Federal Council will meet again on October 17, 2025. Until then, the situation remains unclear but extremely risky.
Chapter 5: Implications for Consumers
- Last legal phase: You can still purchase 1S-LSD at this time.
- Legal risk: Immediately illegal once it takes effect.
- Possession: Unlike some NPS bans, possession will not be exempt.
- Alternatives: Legal substances such as 3,4-ETMC or HHC remain available for the time being.
Chapter 6: Implications for Retailers
- Sales suspension: Effective immediately upon publication.
- Clearance sale: Remaining stock may be sold until then.
- Communication: Stores like HappyFlower provide clear updates as soon as the suspension takes effect.
Table: Overview of current decisions
| Topic | Status | Duration/Procedure |
| Smoking/Vaping in the Car | Ban approved | Effective immediately |
| Nitrous Oxide & GHB | Legislative process | about 3 months |
| 1S-LSD / LSD core | Ban approved | It is unclear when it will take effect |
| 6. Amendment to the NpSG (ETMC, etc.) | Not yet addressed | Expected Oct–Nov 2025 |
Chapter 7: An International Perspective
- 1S-LSD is already banned in many EU countries.
- Germany was one of the last markets where it was still freely available.
- The ban is part of a global trend toward stricter regulation of LSD derivatives.
Chapter 8: What's Next?
The major 6th amendment to the NpSG is imminent. It is expected to ban:
- 10-OH
- 3,4-ETMC
- NB-DMT
This threatens to deal another massive blow to the scene.
Chapter 9: HappyFlower Alternatives
Even if 1S-LSD is banned, you can still find legal and tested alternatives at HappyFlower:
- 3,4-ETMC
- HHC products
- THC shots (in countries where they are legal)
This way, you'll stay on the safe side legally.
