Term can be used to sarcasticly nickname a cigarette. Came about on the basis that cigarettes can cause tumors and a cigarette is shaped in a tube-like fashion.

Infamously invented by the late great Brian Adams.
Can be used by one friend to another in a fitting circumstance to degrade the usage of a cigarette

ie. Yo Son, is ya'll on some wack shit, goin out in this fucking rain just to smoke a god dam Tumor Tube. Ya'll ain't even ballin 10 deep, never mind 12.
