Lord Malcolm P. Glassworthy was the Ninth Earl of Glassworthy, heir of the Glassworthy family fortune, and the oft-revered father of Social Lubrication. MPG, as he was known by his peers, was celebrated in his lifetime as the Johnny Appleseed of cannabis. He led a personal crusade to champion the healing, rejuvenating, and as he called it, the socially lubricating power of the flower.
