1S-LSD – Status, Ban in April 2026 & Legal Alternatives | Happyflower

1S-LSD is a cannabinoid that came under legislative scrutiny in 2024/2025 and has been banned in Germany since April 12, 2026, under the New Psychoactive Substances Act (NpSG). On this collection page, we document the ban status, the legal classification, and the legal alternatives you can buy instead at Happyflower.

Why is 1S-LSD banned in Germany?

1S-LSD was added to the NpSG as a psychoactive substance through the amendment to the NpSG dated April 12, 2026.

The NpSG was introduced in 2016 and has since been regularly updated to include new psychoactive substances. With each amendment, entire groups of substances are added in response to new designer drugs. 1S-LSD was added to the NpSG in 2025, making its trade, sale, and possession a criminal offense in Germany—including online sales.
