Hi all. I have recently switched from hemp oil to cannabis oil (withouth thc, hoping it will reduce my pain. Have only been taking in for 5 days but it has taken no affect. In desperation I do have a prescription for morphine that I have never taken and wondered if anyone knows is it safe to take both? I have pulmonary fibrosis, emphysema and a growth on my lung which is suspected cancerous. thanks in advance for any advice.
