A few refinements could make it even sharper and more impactful, especially if your goal is engagement and credibility.

First, your framing of shifting attitudes is solid. Referencing the rise in legalization in places like the United States gives the reader context, but you might tighten that section slightly to move faster into the hook—because the real attention-grabber is the condition itself, not the policy backdrop.

Where your piece really stands out is introducing Cannabis Hyperemesis Syndrome. That’s the “pattern interrupt” readers don’t expect. The term “scromiting” is especially powerful—it creates a visceral reaction and makes people keep reading. You used it effectively, but you could bring it one paragraph earlier to hook readers sooner.

The middle section is compelling, but you can increase impact by tightening repetition. For example, you mention severe pain, ER visits, and vomiting multiple times—consider consolidating those descriptions into one vivid, memorable passage instead of repeating variations. That will make the story feel more focused and less diluted.

Your use of expert voices (like Dr. Buresh and Dr. Carlini) is excellent—it adds authority. If anything, you could sharpen their quotes slightly or follow them immediately with a clear takeaway sentence so readers don’t drift.

The strongest part of your piece is the conclusion. The comparison to alcohol and tobacco lands well because it avoids extremes. You’re not saying cannabis is “bad”—you’re saying it’s not risk-free. That nuance builds trust.
