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.
Apparently inky caps are completely edible – unless you drink alcohol.
