Mykayla Comstock, a seven-year-old girl who was diagnosed with an aggressive form of leukemia, has a medical marijuana license in Oregon and consumes strong capsules of the drug twice daily, reported The Oregonian.

She is one of 2,201 cancer patients and one of 52 children allowed to use medical marijuana in the state. Her age, however, has stirred controversy and left some wondering whether -- and where -- to draw the line on a drug that can ease the side effects of illnesses and cancer treatment.

One recent international study found that marijuana use among youth whose brains are still developing can damage memory and intellect. Some doctors say that children can be treated with better, less controversial medications .

While Mykayla's mother administers the capsules and occasional cannabis-laced confections, her father, who lives in North Dakota, opposes the treatment, claiming that during one visit she was "stoned out of her mind."

Mykayla says the drug helps her "eat and sleep" and makes her feel "funny, happy."

She is currently in remission, and her mother still administers medical marijuana to her.
