I recently found that one of my first publications has become a historical source. Which is a bit spooky...
John Davis, The
Drug Scene and the Making of Drug Policy, 1965–73
Twentieth Century British History (2006) 17 (1): 26-49.
'...It is important, though, to distinguish this sort of multi-drug use, spurred primarily by the junkies’ search for heroin substitutes, from the poly-drug use characteristic of the wider London scene that was rooted in eclecticism and experimentation. ‘The typical young user’, a Medical Research Council Working Party concluded in 1970, ‘is now much more often a poly-drug abuser than someone exclusively dependent on any one drug.’60 Hard figures are, as usual, hard to find. Elizabeth Tylden’s study of cannabis users found that whereas 80% of users surveyed in 1965 had used no other drug, this was true of only 11% of users surveyed in 1970; the proportion ‘on multiple drugs’ had risen from 2 to 21%.61 Patrick O’Sullivan, working with teenage users in Camden, found that experience increased with age: those approaching twenty had experimented ‘over the years... with most of the “soft drugs”… Through experience and contacts they had therefore built up a good deal of drug knowledge of the kind lacking in those younger groups.’62...'
