Yes exactly! This would be the innate immunity while what I described was adaptive

The green snot comes from neutrophils and WBCs which have eaten some bacteria

Most toxic drugs and alcohol are processed in the liver via a system called the Cytochrome C450 (CYP) system. It’s an enzyme, Most common is CYP is 450 but there’s many types. Certain drugs alter the metabolism or speed of CYP enzymes, thus increasing or decreasing the metabolism of said drug, thus altering its pharmacology

Great question! Physician here. The body has a really neat way of cleaning up infections and a multitude of pathways to achieve it. Typically, once your body recognizes a foreign pathogen and attacks it (either by antibody’s or special cells called T-Cells) it will pick up said offender from tissue and deliver it to the lymphatic system. This a system composed of highways that parallel veins/arteries. Within the lymphatic system are lymph nodes, this is where your body will “sound the alarm” and help to amplify the specific defense against that pathogen. It will break down the bacteria or virus that is encountered and essentially ultimately break down its components to sub unit level where their parts can be recycled.

In the blood, a similar process but with the reticuloendothelial system, one that consists of the spleen, liver, and blood that involve clearing bacteria from the system
