I think classical psychedelics are among the safest drugs, but honestly, how is that not "too much acid"? If they needed medical care, that implies that if they hadn't received that care they would not have been perfectly fine. Yes, it was an accident caused by irresponsible use, but let's not mince words. The point where a dose is "too much" should be (at the most) the point where you need medical attention, not the point where you suffer some permanent damage or death.
