In Marilyn Howell’s second appearance on WGBH’s “Greater Boston” with Emily Rooney, she shares what it was like to be with her daughter as she underwent MDMA-assisted therapy during her final moments.

Typically, when a person is in the end stages, you have a choice: do you want to be asleep, or do you want to be in pain? MDMA gave her the…possibility to be alert, and aware, and back to herself for a few hours…She died with a sense of peace and joy.
