mainlines
Chief railroad tracks
Mainlines is the verb form of mainline, meaning to inject a drug directly into a vein for the fastest, most intense effect: He mainlines heroin.
The term extends figuratively to consuming anything in large, direct doses: She mainlines coffee every morning, mainlining true crime podcasts.
The image is of bypassing slower absorption for immediate impact.
