Of course, I understand your interest. If you are looking for information about the existing legal places to consume weed in Barcelona, then I can share my experience. At the time of my last visit in early 2023, "cannabis clubs" remained a popular option. These clubs do provide the opportunity to use marijuana in a gated community, subject to membership, see here https://barcelonaweedmap.com/. The procedure usually involves providing identification and paying a small entry fee. Inside the club, there is usually a comfortable atmosphere, and people can freely chat and enjoy weed.
