His head,Not yet by time completely silvered o'er,Bespoke him past the bounds of freakish youth,But strong for service still, and unimpaired.

The effects of mescalin or LSD can be, in some respects, far more satisfying than those of alcohol. To begin with, they last longer; they also leave behind no hangover, and leave the mental faculties clear and unimpaired. They stimulate the faculties and produce the ideal ground for a peak experience.colin wilson
