Yes, I have tried most methods. With Leaf, you can find specific types that are high in Caryophines. These work on the CB2 receptor in the brain and thus help reduce pain. The vap cartridges are convenient, and you use what you need. Iowa has a cartridge names "Comfort" which works very well for me. Start slow and low and build up your dosage. Sure beats morphine.

God bless your journey.
