Paula Crews, a suburban mom with short black hair, dumps a stick of butter into a double boiler and stirs in her secret ingredient. Her 24-year-old son, John, waits expectantly at the white Formica counter in their West Broward kitchen, watching while his mom mixes the butter into a pot of melted chocolate. Finally, she pours the candy into a rectangular mold and puts it in the fridge to cool.
A few minutes later, John pops a piece of his mother's creation into his scruffy face. In about a half-hour, the frat-boy archetype in a Guy Harvey T-shirt will be comfortably numb from the marijuana baked inside the homemade candy bar.
"And that's how you make chocolate with canna-butter," Crews concludes proudly. "That's my son's medicine."
