I especially like this part:

Disulfiram has, however, been known to cause myocardial infarction (heart attack). The symptoms can occur if even a small amount of alcohol is consumed up to three days after eating the mushrooms, although they are milder as more time passes. Rarely, a cardiac arrhythmia, such as atrial fibrillation on top of supraventricular tachycardia, may develop. Because of these effects, in some cases, the mushroom has been used to cure alcoholism.

Everything about that is wild.

That's wild. Makes me wonder if it was ever weaponized by temperance movements.

Interesting; apparently there are no known cases of anyone dying from it, but it stops ethanol from metabolising properly so like with antabus you mostly just feel like shit for a while. So it sounds like an actually useful treatment for alcoholism.
