The pipes date to the seventeenth century when hemp was used widely in the production of rope, clothing, and paper, and when marijuana was used to treat certain medical conditions. However, the discovery of the pipes laced with several narcotics lends credibility to the theory that people in Renaissance England used drugs for pleasure.
It has been a long-standing but highly unconventional assumption that Shakespeare alludes to drugs and drug use in his works, particularly in his non-dramatic poetry. Sonnet 27 begins:
Weary with toil I haste me to my bed,
The dear repose for limbs with travel tired;
But then begins a journey in my head,
To work my mind when body's work's expired. (1-4)
Even more conspicuous is Sonnet 76, which contains Shakespeare's references to a 'noted weed' and 'compounds strange' -- 'compound' known as early as 1530 to mean a substance formed by a chemical union of two or more ingredients:
Why is my verse so barren of new pride,
So far from variation or quick change?
Why with the time do I not glance aside
To new-found methods and to compounds strange?
Why write I still all one, ever the same,
And keep invention in a noted weed,
That every word doth almost tell my name,
Showing their birth and where they did proceed? (1-8)
And Sonnet 118 divulges:
Like as, to make our appetites more keen,
With eager compounds we our palate urge. (1-2)
There is little doubt that this combination of the findings by South African researchers and the possible references to psychotropic drugs in Shakespeare's writings will prompt many more to hypothesize that Shakespeare used narcotics as a source of inspiration. We will never know for sure, but if Shakespeare did use drugs as a tool to spark his creativity he certainly would not be the only literary genius to have done so.
