A seven-year-old girl suffering from leukemia is one of Oregon’s youngest medical marijuana patients. Her mother says she gives her daughter marijuana pills to combat the effects of chemotherapy, but her father, who lives in North Dakota, worries about the effects of the drug on her brain development.

Mykayla Comstock was diagnosed with leukemia last spring. Her mother treats her with a gram of cannabis oil daily, The Oregonian reported.

Mykayla’s mother credits the drug for the leukemia’s remission. “As a mother, I am going to try anything before she can potentially fall on the other side,” said Erin Purchase, 25, who with her boyfriend administers Mykayla’s cannabis.

The girl says the drug helps her eat and sleep but also makes her feel “funny.” “It helps me eat and sleep,” Mykayla said. “The chemotherapy makes you feel like you want to stay up all night long.”
