I don’t think weight loss is vanity (assuming that’s what you mean). There are many health issues caused by obesity, and a lot of us end up paying for the advanced medical care (regardless of being obese or not) for obesity-caused illness through increased premiums and taxes to cover high Medicare costs.

It's not a vanity drug if you're obese due to genetics or side-effects of other medications.

It's myopically arrogant to throw shade with a big brush over fringe cosmetic uses when there's an incredible amount of benefit offered to formerly morbidly-obese individuals and people with seriously decompensated metabolic-associated diabetic conditions. Yes, GLP-1's are absurdly overpriced mostly in America where there are comparatively few healthcare consumer protections.

You can make it for less than $1 per gram. So, it costs about $10 per month.
