Yes, you could water cure it. Get a mason jar or glass and fill it with water, submerge you cannabis in the water and put something on top to keep the matter submerged.
Everyday change the water, and do this for about 3 days.
After 3 days take the cannabis matter out and leave it out to dry which should take a day or so.
This will remove all taste and smell from the cannabis, so any potential quality's it had with be lost apart from the THC and stoning bits.
