Thousands of people from around the world came to learn about the benefits of medical marijuana.

Hector Elizalde said it changed his daughter’s life. The 9-year-old girl had hundreds of seizures and not even brain surgery could stop them.

The conference continues Saturday at the David L. Lawrence Convention Center downtown.
