But I think they are "normal" left wing policies in Europe in the sense that parties in various countries/cities/regions have campaigned on them or implemented them.

You are getting downvoted because that statement is false dichotomy. Left wing drug policies are about affordability and access. Nationalization is one extreme rare end of that but far more common are negotiations and regulations of prices.
