I think the best oil cartridge would be an AC/DC strain specific cart. A higher CBD strain should mitigate the negative aspects of your arthritis, though I think there is a better option if your arthritis is in your extremities.
Topicals are a great way to medicate! I have recently fallen in love with this stick from Om Edibles. It’s their Lion Balm preparation, but it come’s in this super convenient stick so you do not get the balm on your hands. Great for at work when your typing, but you don’t want goo on your keyboard.
