SAO PAULO — The 4-year-old boy struggled to balance while walking through the living room. His mother's eyes attentively followed his every move. Then a seizure knocked him to the ground, the dull thud of his small body echoing through the home.
On this July morning in Guaruja, a coastal city in Brazil's state of Sao Paulo, Murillo quickly regained his senses as his mom, Janaína Silva, cradled him.
''From five minutes of agony, it's now just seconds," Silva said, recalling how only three months ago her son's seizures would have lasted much longer. Murillo was diagnosed as a baby with Lennox-Gastaut syndrome, a type of epilepsy with multiple types of seizures that cause stiffening and dropping of the head and limbs.
Silva believes his shorter — and less intense — seizures are a result of a steady dose of liquid cannabidiol (CBD) that she can acquire for free through the state public health system. It's a step the federal government has failed to take, as legislation to regulate medical cannabis and its derivatives at the national level has stalled in Congress for years.
In drugstores, a 30 milliliter bottle (1 fluid ounce) of the CBD that Murillo's pediatrician prescribed for his condition costs as much as 900 reais ($180) — more than half Silva's monthly wages as an office assistant. Since June, she has spent zero on Murillo's CBD medication. Twice a day, she drips the oil into the boy's mouth, and each bottle lasts about 45 days.
CBD is a chemical found in marijuana and some studies have shown it helps reduce seizures in people with severe forms of epilepsy when taken in combination with other medications. It's not yet clear why it reduces seizures, and side effects can include diarrhea, vomiting, fatigue and sleep problems. CBD is not the compound, THC, that causes marijuana's high and has been shown to help cancer patients and other sick people improve their appetite.
Sao Paulo, Brazil's most populous state with over 44 million people, was the first to enact legislation making CBD available for free.
The law was a win for Brazilian moms who have led a decadelong campaign to secure access for their sick children. They have fought through civil disobedience, court petitions, marches and political pressure.
