““The effects of what are now called psychedelic (mind–manifesting) chemicals differ from those of alcohol as laughter differs from rage or delight from depression. There is really no analogy between being “high” on LSD and “drunk” on bourbon. True, no one in either state should drive a car, but neither should one drive while reading a book, playing a violin, or making love. Certain creative activities and states of mind demand a concentration and devotion which are simply incompatible with piloting a death–dealing engine along a highway.””
