Google cannabis and chronic fatigue syndrome and you’ll get lots of speculation and questionable info, but pretty much no scientific research whatsoever. That’s because chronic fatigue—sometimes known as CFT/ME (the “ME” stands for myalgic encephalomyelitis, which might be a more medical-sounding synonym for CFT or might be its own ailment)—arouses nearly as much controversy in the medical world as cannabis does.
A disease seemingly with no cause but a laundry list of symptoms that includes fatigue (duh), loss of memory or concentration, swollen lymph nodes, and sore throat, muscles, and joints, CFT entered the popular consciousness in the 1980s, when it was nicknamed “the yuppie flu.” That gives you an idea of how not seriously it was taken by everybody—except those who languished from it.
This skepticism has tapered (slightly) over the decades. However, last year in
a densely-sourced report, the Institute of Medicine finally weighted in, giving its imprimatur to CFM/ME—to which it proposes yet another name-change: “systemic exertion intolerance disease,” or SEID.
The official line is now that the disease formerly known as chronic fatigue is indeed a bona fide disorder; we just don’t know what causes it.
