Inadvertent Mind Control

The poison I inhale is Marlboro,
but sometimes I buy Pall Mall
to save on the price of a carton of milk
and maintain my smoker's cold and cough through all the summer days,
Undermining my prospects in any number of other ways.

When convinced I requested Pall Malls I'm occasionally given
the Marlboro Golds.
While accepting the mistake as mine, alongside the error of
an expensive habit that has killed billions of my betters -
I will doubletake at the shop-assistant -
and whenever this happens, silently wonder
if my mouth says Pall Mall Blue,
but my eyes say Marlboro Lights.
