In what way? I mean, sure they grow and some are a 50/50 of thc and cbd. But are you asking if what they have is good for pain?
CBD seems to do more for seizures or semi related brain problems....But I'm sure there is a relative between all the compounds and what you seek.
CBN the result of "old" or breaking down thc seems to have a better relationship to pain relief.
I run my plants out 1-2 weeks longer then the seed breeders say to. But that is a "rule of thumb" that simply gets better peak quality in my book.
There are MANY good for pain strains out there.....maybe you should ask that.
Here's a few that my patients like for pain relief.
Exodus Cheese - Kaliman seeds
Kushage - THseeds
Humbolt - given clone
Chem Dawg - not avail from Cali connection any more
OG kush (ghost cut) - Dr greenthumb
There are MANY strains that work well,,,just ask
