Lay off the crack
I wrote a 6 page Word doc, thats what I meant. I want people to challenge my theory but I need to learn my stuff first.
Disease is a detoxification, so the subject has been poisoned/intoxified (my word). Symptoms occur due to the detoxification process. When we are healthy our cells self-repair and this is an unnoticeable detoxification process. When we get diseased, it's usually because a critical mass of toxicity has been reached (though there are other triggers) and the brain takes over and creates symptoms which accelerate the detoxification.
Illness is a more generalized and nonspecific term referring to a general state of unhealth. Similar to sickness.
And you didn't ask, but disorders appear to either entirely or much more psychological i.e. behaviour related, e.g. staying up late leads to sleep disorders.
Drug effects are actually drug withdrawal effects. The effects of a drug are the effects of the withdrawal of the drug. When you consume a stimulant, your heart beats faster (tachycardia), your temperature tends to elevate (fever, even if mild), you pay increased attention to your mental state and otherwise your actions (thought acceleration, thought organization). All of these are ways in which the body is ridding itself of the poison (i.e. it's detoxification).
The body, quite broadly, always seeks homeostasis. It always seeks to remove xenobiotics. When you consume a substance your body immediately begins processing it, either detoxifying it or otherwise.
See, interesting stuff isn't it? Seems like the average person and even very many drug-users (including nootropic users like many on Longecity) don't know this stuff.
On this topic, I posted months ago about some mystery shortness of breath I kept getting. Its 90-95% resolved now, seems to have done it on its own. I still haven't found out what caused it and might never will. In line with my theory I suspect it was a detoxification, but of what I don't really know.
