CBD is used for the symptom relief from cancer such as pain, sleeplessness, neurological complaints, immune support and much more. There is no "high" from CBD and it can be purchased from many sources. Picking a good source can be tricky. I look for nanotechnology and have a product I wholeheartedly endorse (NuLightCBD.com)
THC has its forte with nausea associated with cancer. Cancer pain can also be controlled with THC. I prefer this usage primarily because it is efficacious but also avoids use of opioids. There are many strains based upon what you may need. I certainly support medical cards ("red cards" in Colorado) to those who qualify and can assist you in acquiring this for your cancer battle.
