There was a piece of law that passed on weed. Here's the wiki:

The German cannabis control bill (German: Cannabisgesetz) is a bill passed by the German Bundestag in February 2024, and the Bundesrat in March, that legalised the adult (18-years-old and over) use of cannabis in Germany, as well as the personal possession and cultivation of limited amounts of cannabis by adults in Germany, beginning on 1 April 2024. Adults in Germany are allowed to possess up to 25 grams of cannabis in public and up to 50 grams of dried cannabis at home. Each individual adult in Germany may also have up to three of their own cannabis plants at home. As part of the bill, adult-only non-profit cannabis social clubs with a maximum of 500 members will become legal in Germany from 1 July 2024.
