There are literally thousands and thousands of different strands of marijuana but they will all be classified as either Sativa, Indica or Hybrid. Its hard for me personally to get my hand on any medical grade marijuana or cannabis oil because of where I live (Kansas), but I still have 10+ years experience using marijuana on my own and will say that smoking mj helps my crohns symptoms. It helps with my pain, nausea, increases my appetite which is almost non existent during a flare-up. It also helps me relax and to sleep better at night. Marijuana really does help and if you live in a state where its legal and readily available I suggest you make a few calls to your medical marijuana supplier and go over with them your symptoms and what kind of relief you're looking for. I would definitely get a high CBD/high THC cannabis oil to put in capsules to either swallow normally or to use as a suppository. If you don't want that euphoric high feeling then just find a strand that is low in THC and high in CBD. Me personally I want an oil that is high in CBD AND high in THC. Best of both worlds because THC does have medical benefits even though the media likes to down play THC and make it all about CBD and that shouldn't be the case at all. Now I wouldn't want a minor or a child on a high THC strand but as a 30 year old adult I wouldn't hesitate to use that kind.
