Do you know under what circumstances they went off on their trip?
One guy got a teat pipette full of it emptied into his eye, funnily enough at Glastonbury. He went from being a clever clogs sporting type to spending most of his days sitting in his room staring into space.
I think the others were squat party burn outs in general so they may have been heading for it anyway, but it certainly wouldn't have helped.
Sounds pretty much just as expected then.
I still haven't found a single case where responsible use resulted in anything other than positive experiences. You're basically concluding that alcohol is unsafe because somebody chugged bottles of scotch and sustained permanent braindamage.
