“This is your brain on drugs”

“This is your brain on drugs” is an antidrug campaign slogan introduced by the Partnership for a Drug-Free America in 1987. In the book, its force as a memorable public image is sharpened by a contrast with scientific brain imaging: the human brain affected by methamphetamine does not resemble the campaign’s famous fried-egg comparison, but appears instead as a field of activity likened to the night sky over Baghdad during the opening weeks of war.

Campaign and Image

The slogan belongs to a campaign that made the brain visible through an instantly recognizable analogy. The narrative does not present the phrase as a medical finding; it places the campaign image beside a more complex account of what researchers could see using functional imaging. That shift—from a simple emblem to a measured picture of brain activity—changes the scale of the discussion without erasing the slogan’s cultural familiarity.

The Scientific Counterimage

The contrast takes shape around Edythe London, a pharmacologist and professor of psychiatry and biobehavioral sciences at the David Geffen School of Medicine at UCLA. In 2000, she made images of the brains of sixteen methamphetamine abusers. After admission, the participants slept in the hospital for two days, as many people stopping methamphetamine do; several days after they awoke, London used positron emission tomography, or PET, to map their brains.

What the Scans Measured

PET scans register brain activity through blood flow and biochemical reactions traced by radioactive markers. Depending on the marker, a scan can show general activity or activity associated with a specific neurotransmitter; the resulting images can also be related to emotion. London’s research focused on the brains of methamphetamine users in the initial stages of withdrawal—the condition of people entering rehabilitation. Against this account, the slogan’s fried-egg image reads as a blunt point of reference, while the scans offer a more differentiated picture of brain function.
