Nearly every market where the quality or efficacy of the product isn't readily verifiable by the purchaser is a hotbed for scams and snake oil.
We allow gas stations to have diesel pumps right next to gasoline ones. We just require that they be labeled appropriately and its expected that people read the label and not make assumptions based off proximity.
OTC medical matter isn’t regulated anywhere as tightly as active drugs. They’re supplements or food additives or other such things. Whole lot of that shelf space goes to stuff that’s not as useful or desirable as people think. And any ambiguity is naturally exploited to the max.
Also, even in America I think you can order contacts and glasses online without a prescription; you just have to know your numbers.
Here in Japan, you do not need a prescription to buy contacts; you can just write down your numbers on a form and buy them over-the-counter.
If the consumers want it I have no problem with a section of homoeopathic stuff. I do have a problem with it being mixed in.
If freaking 7-11 stores can sell me Aspirin tablets, I don't see how Whole Foods can't.
So that's always in my drug cabinet now so that I won't have that situation again.

> It is an opioid with no significant absorption from the gut and does not cross the blood–brain barrier when used at normal doses.
The "morphine giving you constipation" thing... this is the same, except that's all it does.
I'll also note the WHO Model List of Essential Medicines - https://en.wikipedia.org/wiki/WHO_Model_List_of_Essential_Me... - its under "Medicines for other common symptoms in palliative care" as Loperamide.
The most intuitive is prolonged use can stop all waste leaving your system for a while. As you can imagine, when the system finally starts going again it's initially uncomfortable, and can also be long-term damaging.
> The primary intent of users has been to manage symptoms of opioid withdrawal such as diarrhea, although a small portion derive psychoactive effects at these higher doses. At these higher doses central nervous system penetration occurs and long term use may lead to tolerance, dependence, and withdrawal on abrupt cessation. Dubbing it "the poor man's methadone", clinicians warned that increased restrictions on the availability of prescription opioids passed in response to the opioid epidemic were prompting recreational users to turn to loperamide as an over-the-counter treatment for withdrawal symptoms.
The fact that it doesn't happen suggests that either they don't care - or they have some interest in maintaining the confusion.
