Endnote 5 — 'drines, and Pemulis's abstinence

Identifies "'drines" as amphetamine-family stimulants, "lightweight speed" (p. 983) like Cylert, Tenuate, Fastin, Preludin and Ritalin. Notes that Pemulis, out of a blue-collar honor code, rarely takes them before a match and saves them for recreation; the sub-note singles out Tenuate (diethylpropion) as his hoarded personal favorite, quietly pilfered by his roommate Jim Troeltsch.
