Medical marijuana advocates protested to no avail Thursday as a second House committee advanced statutory limits to an active ingredient in the plant medicine.

Legislation that would establish maximum caps for THC levels in Florida’s medical cannabis program is now one step from the House floor, having cleared the second of three committees on a 9-6 vote.

A version of this bill has passed the House before.

However, despite having passed the Health Care Appropriations Committee Thursday, there’s still no certainty THC caps could become law this year regardless of House approval.

The bill (HB 1455), sponsored by Rep. Spencer Roach, would limit the controversial compound levels to 10% for smokable marijuana and 60% for concentrates.
