A three-year-old cancer patient is responding well after his mother switched from chemotherapy to medical marijuana.

Sierra Riddle, mother of three-year-old Landon, relocated her family from Utah to the legal medical pot state of Colorado after chemotherapy caused her son to suffer nerve damage, intense pain and a complete loss of appetite for 25 consecutive days. Ms. Riddle investigated medical marijuana and made the move to Colorado Springs where Landon’s leukemia was treated with liquid forms of both THC and the non-psychoactive cannabis compound cannabidiol (CBD).  

Within four weeks of pot therapy, Ms. Riddle said Landon not only regained his lost appetite and energy but that the cancer went into remission – a result consistent with clinical research indicating that CBD in particular has demonstrated the ability to halt metastasis in aggressive cancers.  

However, Ms. Riddle encountered another hurdle when she received a visit from a Colorado Human Services caseworker last week after a physician reported her for refusing to treat her son with chemo.

Ms. Riddle told CBS4: “They are not only forcing me to do something against my will as a parent, they are forcing me to make my child sick.”

When a reporter asked Ms. Riddle if medical marijuana treatments were helping Landon, she responded: "Yes, a hundred times better, I mean a million times better.”

Ms. Riddle’s confidence in marijuana’s efficacy underscores the increasing movement across the US for children with serious ailments to be treated with medicinal cannabis. Parents like Ms. Riddle just want what’s best for their child and have found that marijuana works.

“As soon as we started taking the oil, his platelets have been a regular healthy person’s level and [doctors] can’t understand why,” Riddle explained.
