Some people have accidentally taken several milligrams of LSD, whose full active dose is 100 ug, and they are fine. Every molecule's effects saturates at some point.
And this is not a one-off thing, but a monthly regimen. So we're talking about taking a dose that's way beyond heroic, every month, for the rest of your life. That's so far outside the realm of responsible psychedelic use, I don't think any human has even come close to attempting it. The only thing that's for certain is there's no way of knowing what the psychological effects would be, but I have a hard time believing it wouldn't get extremely ugly.
