Dr. Sanjay Gupta, a neurosurgeon and CNN Chief Medical Correspondent, used to be an opponent of medical marijuana. Last year. after looking into the research, he changed his mind. Now he is "doubling down" on his position that marijuana is effective medicine.
Since our documentary "Weed" aired in August, I have continued to travel the world, investigating and asking tough questions about marijuana.
I have met with hundreds of patients, dozens of scientists and the curious majority who simply want a deeper understanding of this ancient plant. I have sat in labs and personally analyzed the molecules in marijuana that have such potential but are also a source of intense controversy. I have seen those molecules turned into medicine that has quelled epilepsy in a child and pain in a grown adult. I've seen it help a woman at the peak of her life to overcome the ravages of multiple sclerosis.
I am more convinced than ever that it is irresponsible to not provide the best care we can, care that often may involve marijuana.
I am not backing down on medical marijuana; I am doubling down.
