<s>[INST] Hi, My 87 yr old Mom has lung stage iV cancer. One Doctor recommended to take a tablet manufactured by Roch (maybe $100 per tablet) per day. My Mom is very thin as she does not have appetite to eat. My Geriatrician friend advised us not to take the tablet because of side-effects. Palliative care is her recommendation. My question then is that, can medicinal marijuana be used for my Mom to alleviate pain instead of taking pain medicine or for pain management? Thank you [/INST] Thanks for your question on HCM.I can understand your situation and problem.Stage 4 lung cancer gives a lot of pain.And pain management is integral part in palliative care.Yes, you can give medical marijuana.You can also try transdermal patch of tramadol. It is also centrally acting pain killer.It's action last for 72 hours. And given especially in terminal cancer pain.So ask your doctor about it. </s>
