It's easier to claim that Shlomo had tripped on LSD that he had been slipped than to suggest that he'd taken it intentionally, but i've never heard of him denying having tried it, ostensibly for some combination of perspective and local credibility. Moish Geller maintains that Shlomo was not only dosed by hippies, but that he had once done a very intentional session with another Rabbi, during which he was to ask the other rabbi a series of questions. According to the story, Shlomo instead asked questions like: What do your children love? and What does your wife need from you? The responses compelled Shlomo to conclude that tripping LSD put someone in a state where only that which was most important to them was real to them. Shlomo is never described PURSUING psychedelic experience, certainly not grass, dismissing drugs as "diapers" and inferior to the real work of love and attention to human need. That said, he is not often depicted refusing joints too aggressively, especially when it's part of a communal initiation, and a form of demonstrating that he was part of a hip in-group. This was a beautiful article, by the way, one of the richest descriptions of the experience of Shlomo at it's most intimate in a little while. Thanks!
