I don't know if the oil in it is in any way cannabis derived, but there is a product called "Relief Factor" [ https://www.relieffactor.com/ ] that's heavily hyped over here in some radio-TV-magazine testimonial/celebrity endorsement type advertisements as [supposedly] very effective against persistent pain taken regularly over time. It [supposedly] works on the same basis as apparently claimed for the CBD oil, by reducing “inflammation”, I assume[?] at the cellular level.
The Relief Factor product is also much more expensive than I would have thought after reading the ingredients, and I am very, --- more like extremely, skeptical of it actually working as claimed. It would be great if it did, but ….... However, they do offer a 3-week trial amount at a reduced price which I have been thinking about getting for an elderly relative to try so she might possibly be able to reduce the alarmingly high amount of opiates she's having to take now.
I have no idea if it would actually be a genuinely good and viable option should the CBD oil not work out as well as hoped, but it might be something to be aware of
