        “I actively searched for someone to tell me how they’d made an informed and calculated choice to use chems and, that for them, the chem scene is just recreation.” […] “Even those who told me sex on chems made them feel ‘like a don’ would follow up such celebratory statements with tales of rejection, regret, loneliness and longing for intimacy,” he said.

      • 2017, James Wharton, Something for the Weekend‎, Biteback Publishing, →ISBN:
