Proposal to cap THC in medical pot emerges in the Florida Senate

A plan to limit medical marijuana’s potency is gaining support as the 2020 Florida Legislature moves into its final two weeks.

On Friday, Sen. Gayle Harrell, a Martin County Republican, filed an amendment to a bill (SB 230) involving the state Department of Health that would cap the level of tetrahydrocannabinol (THC) – the chemical agent that causes the high – to no more than 10 percent in medical marijuana products for patients under the age of 21.

Physicians could exceed the cap if they certify the patient is terminally ill.

The Senate Rules Committee is scheduled to review the bill, along with the THC cap amendment, on Monday.

House Speaker Jose Oliva, a Miami-Dade County Republican, and other House leaders have pushed for a THC cap, arguing that at least one recent study shows possible links between high-potency cannabis and psychosis in some users.

The Senate rejected a similar proposal last year. But Senate President Bill Galvano, a Bradenton Republican, has said his chamber is open to considering the proposal in this session.

Sen. Jeff Brandes, a Pinellas County Republican, and veterans group earlier this week urged the Senate to reject the House’s attempt to impose a 10 percent THC cap.
