>> at home in colorado paige searched for marijuana high in cbd. that's the ingredient some scientists think helps seizures and also low in thc. remember, she didn't want to get her daughter stoned. she found a small amount in a denver dispensary. the owner was surprised that anyone would even want it. >> they said it's funny because no one buys this. that was the general consensus, no one wanted it. it didn't have any effect. >> paige paid $800 for a small bag and took it home. >> i had a friend that was starting a business making medicine, and i said can you help me extract the medicine from the bag of marijuana? i measured it with a syringe and squirted it under her tongue. it was exciting and very nerve-racking. >> holding charlotte in her arms, paige waited. an hour ticked by. then another. then another.
