Cannabis isn’t a miracle cure for most people, but it worked like Lourdes water recently for a young boy with a form of non-verbal autism.

9-year-old Kalel Santiago of Puerto Rico hadn’t said a word until he was administered a CBD extract spray earlier this year, according to Yahoo Parenting. He was hospitalized as an infant with a rare cancer known as neuroblastoma. Because of the rigorous series of surgeries, radiation treatments, and chemotherapy undergone by Kalel in his life’s first few years, his unusual behavior wasn’t given full attention until his recovery.

After studying his muted speech and other characteristics, he was diagnosed with severe, non-verbal autism. The boy’s parents, Abiel Gomez and Gladys Santaigo, tried several schools and therapies before being handed a free bottle of CBD at a fundraising event for the surf-therapy school Kalel was making progress in. The oil came from Hemp Health, a California-based company.

After just two days of two sprayed doses per day, Kalel said his first words. At school, he recited the vowels: “A-E-I-O-U.” No report on if he got to “sometimes Y,” but it’s still early.

Abiel Gomez Santiago told Yahoo, “You can’t imagine the emotion we had, hearing Kalel’s voice for the first time. It was amazing. The teacher recorded him and sent it to my wife and me and we said well, the only different thing we have been doing is using the CBD.”

Kalel, like his namesake Superman, has found his affliction’s kryptonite. Hopefully, CBD extract can work the same for other kids suffering similar afflictions, and it won’t work like that weird red Kryptonite in Superman III that creates an evil version of them who has to laser-eye fight the child to the death in a junkyard.

Abiel also added something that you should send to your mom if you want her to cry. Soon after Kalel mastered vowels, he started stringing them together with consonants to form whole words. “He said, ‘amo mi mama,’ ‘I love my mom… I don’t know how to thank [the CBD oil makers].”
