I might have a stomach ulcer, I have been taking some prescribed drugs for it for the last month. I'm about to be off the meds next week, and hopefully my stomach should be better. I was thinking I might get into a little MDMA, or K. I know that these drugs are not good for ones stomach, and could actually cause ulcers. I was wondering if anyone knew if snorting MDMA, or K, would have a harsh effect on my stomach. When snorted do these drugs effect the stomach at all?
