humans spit because they want to get something out of their system.
humans dont just spit because its "habit". it always has deeper meaning.
So while spitting, there is toxins that get out with the saliva.
So if someone spits a lot its usually a good sign. their detox is working.
people have strong urge to spit rather than swallow. if you swallow, the toxins won't escape the body.
