I don't have Crohn's, but I do have pretty severe IBS and another friend with Crohn's, so I can definitely empathize. This is what I use cannabis to relieve, though. It helps better than any pharmaceutical, with no side-effects.
I use (vaporize) Shishkaberry on a daily basis, as well as Violet Delight (doesn't work as well, but it's less stoney). Both are a Blueberry cross (or so my grower says) and I hear Blueberry is generally a good strain for digestive issues. It is also indica dominant, so I agree with the rest of the crowd here on indicas. I would recommend you try eating it for longer pain relief, though, and maybe Rick Simpson oil if you can get it. I know smoking/vaping is great for instant, but you might get better results from ingesting if your system can handle it. You lose alot when smoking/vaping...eating it is more efficient and you keep some cannabinoids that really make a difference.
Take it easy! I hope this helps.
Most Blueberry is Indica dominant , there is however a Blueberry sativa
that you don't see very often.
The majority of the Blueberry crosses that are still indica dominant will
work quite well , one friend with Crohns pretty much sticks to the Blue crosses
and then Romulan ( and NO Romulan is NOT a straight Indica) along with
Rhino and a doubled uo AfGoo I've had for years.
Me , my pain is different than Crohns so I'm not sure how applicable
any info might be , that said I still find much of value in certain genetics
that are out of vogue right now , a good many of which have a more Sativa
component than is popular with the marketplace. Besides Blueberry I kind
of have a thing for Skunks , T'Wreck and it's crosses and certain sativas
that go back to the '70s , some of which are actually pretty fair for pain relief.
But then again you won't see some of this at dispensaries , stuff that
would be likely to be readily available along Indica lines would be things
like GDP and the rest of it's subsets , you might see Rom or the Rhino , the
L.A. Confidential or ReCon would be good , the heavy Indica *REAL* Kushes
( don't get me started on why a great many OGs are NOT a Kush) Aurora
Indica , Black Domina is ( or was for me keep in mind grow techniques have
their effects) a good producer and almost narcotic but at the expense of taste.
One that I can personally recommend that you don't see around much is
yet another Blue cross , the Barney's Farm Blue Moonshine is * very* nice
very effective for my bone on bone orthopedic pain..
And then we have have the old reliable , the one that has kind of gotten
shoved over in the corner and forgotten but whose genetics surface in some
surprising places. I've done these for years and though they might not test
at W.W. or AK type THC levels it consistently produces very high CBD counts
that being the old ubiquitous Calif Hash Plant , a short squat inbred , almost
as ugly as the Rhino , couldn't kill it with a baseball bat tough little plant.
Another that's bombproof that you don't see often is Green Poison , short
finishing , big yielding , shrugs off most of the fungus type pests , however
effect ihas such intensity as to almost be harsh in a way.
A good Master or Pre '98 Bubba would be good along the Kush lines and
the landrace Afghans , Paks and Hindus are around if you look hard enough.
