I expect a relatively small percentage would be interested in dangerous chemical highs if they aren't leading miserable lives they need to escape from. Myself, in that situation would likely spend my time socializing, playing games, consuming various media, and generating some amount of my own content. On a larger scale, I expect that if half the population didn't/couldn't work, but was allowed to live comfortably anyway, there would be a considerable increase in experimental creativity and social functions. We'd all essentially go out and find things to do together and alone.
