The Plutonian Drug is, in my opinion, among my best in the genie of science-fiction. For one thing, it is the sort of tale that can hardly become "dated" in spite of changing vogues and varying themes. And it has the advantages of conciseness and brevity.

The field of speculation that it opens is a fascinating one, and hardly to be exhausted. Benjamin Paul Blood (and, no doubt, others) has hinted that our deepest perceptions of reality may come to us beneath the influence of drugs: a proposition equally impossible to prove or disprove. Quien Sabe?
