That Francis Crick was under the influence of LSD when he discovered the double helix structure of DNA is a widely circulated myth, but I've seen no evidence for it. In “Francis Crick: Discoverer of the Genetic Code,” Matt Ridley clarifies that while Crick did experiment with LSD, it was not until several years after the discovery of the DNA structure. The discovery itself was a result of rigorous scientific research based on experimental results, including the X-ray crystallography of Rosalind Franklin.
