I think there's a small kernel of truth here, but I'd be careful with the conclusion. ABO blood type does seem to correlate with some things. For example, type O has been linked with higher odds of H. pylori/ulcer risk in some studies, but that's a population-level association, not "all type O people have bad stomachs." Crohn's also isn't caused by junk food or blood type; it's a complex immune/gut-microbiome/genetic disease.
So I believe you that your family has GI issues, but that could be shared genetics, H. pylori exposure, diet, stress, meds, &c., not necessarily "O blood." Also, I'd be careful framing subq use as a safer workaround. Instant hives and racing heart from 6-APB sounds like a serious reaction … watch out for anaphylaxis!
Btw, there's a theory that Kurt Cobain's stomach pain was caused by scoliosis exacerbated by the fact that he wore his guitar left-handed which only increased the spinal curvature. This has been known to effect the stomach, so the band being on tour only made Kurt's symptom's worse. Personally though, I suspect it had a lot more to do with anxiety and heroin, but who knows?
