MONTGOMERY, Alabama — Alabama lawmakers took a step toward effectively legalizing a marijuana extract that doesn't get people high, but can be used to treat certain medical conditions.

The Senate Judiciary Committee on Wednesday approved a bill aimed at allowing people with certain illnesses to possess the oil called cannabidiol, also known as CBD oil.

Sen. Paul Sanford, R-Huntsville, says the oil does not make people feel high, because it is low in marijuana's psychoactive compound.

Parents of children with seizure disorders are supporting the legislation. Anecdotal evidence suggests CBD oil can be used to treat the debilitating condition.

The bill would give parents and patients a justifiable defense if charged with drug possession because of the oil.

Sanford says his legislation is separate from efforts to legalize marijuana for medicinal or recreational use.
