COLORADO:  A bill that cracks down on large unregulated medical marijuana grows owned by caregivers was amended Monday in a House committee to allow a student’s prescribed medical marijuana onto school property.

Jack’s Amendment is named for Jack Splitt, a 14-year-old middle school student from Lakewood, whose mother testified that her son cannot attend school while medical marijuana is banned from school property.

Splitt has dystonia, a neurological movement disorder that causes his muscles to contract uncontrollably, and spastic cerebral palsy, both of which are helped by medical marijuana.
