You may want to try glycerine tinctures for your pain,(I use food grade vegetable glycerine) I have been experimenting with them recently, there is not much infos on them. You can make the pain killer in about 45-60 days which is not meant to get you high or you can heat it up in a crockpot for 8 hours (not sure on the settings I have only done this one in a double boiler) and it's more of a knock you on yo butt high.
It's hard for me to see what it really does because I smoke so much pot, and I enjoy smoking it ... I am not a big fan of edibles in general. I have used the tinctures when I am working somewhere that I can't smoke when I need a thc fix and it so does the trick.
I have a few people that have tried my tinctures so far, with random pain or reason ...
One guy said that the cold press stuff (45-60 days process) was helping him sleep but he felt groggy in the morning (someone that rarely smokes)
A woman with fibromyalgia (spelling??) said that both the heated stuff and the cold stuff were easing her pain, but she didnt feel the high when using the cold stuff, however she smokes pot daily and the cold stuff that she first tried was made with trim so I am looking forward to see what she has to say about the new stuff made with buds.
Another close friend said that it takes the edge off at night and help her sleeps, she hasnt slept so well in years and when she sleeps well she has less pain the next day (I think she arthritis...)
Anyway I dont sell any, I just made it for myself and wanted to see if it could really help people with chronic pain. I dont feel like it does anything for my tendinitis problems, but it's definitely has some good medicinal properties so you might want to look into it.

The last couple batches, I was using 1 oz of buds that I grounded and dumped into a 500ml mason glass jar, so that would be around 300-400 ml of glycerine I am guessing. I buy the glycerine at a local health food store. Next time I will just put as much pot in the jar as I can because I want it to be potent enough to use droppers instead of half teaspoons for measurements.
