What house-hold substances are deemed 'illegal substances' during a fight?

I was wondering what house-hold, non prescription substances could be used to gain unfair advantage and to what extent they are allowed.

For instance, would fighters stack up on caffeine/basic painkillers or anything to get the extra edge? Or do those kinds of things only set you back?

This is just me being very unknowledgable about this kind of stuff, wondering what regulations are in effect.

Thank you! It feels good to know what little I can/do contribute here is being used.

Don't sweat it, the advanced search has actually been gone for some time and looks like it just made its return (like within the past couple of days)
