Description

Drug craving that grows during abstinence, called incubation, may share a common brain switch across drugs, and one lab found that switch in a signaling pathway for cocaine and sugar. Fernando Cano and co-authors asked in 2026 whether the same switch drives methamphetamine craving. Rats of both sexes self-administered the drug for ten days, then waited a month while craving incubated.

A drug that blocks the pathway, everolimus, had stopped cocaine and sucrose craving before. Here it did nothing at either dose, and the pathway showed no rise in the relevant brain regions. The authors conclude that methamphetamine's incubated craving runs on different machinery, so treatments may need to be drug-specific after all.
