I don't get it but I'm not sure I'm supposed to.

    life + death = mortality
    life - death = lifestyle

    drug + time = occasion
    drug - time = narcotic

    art + artist + money = creativity
    art + artist - money = muse

    happiness + politics = contentment
    happiness + art      = gladness
    happiness + money    = joy
    happiness + love     = joy

    Life + death = mortality  

is pretty good IMO, it is a nice blend of the concepts in an intuitive manner. I don’t really get

   drug + time = occasion

But

   drug - time = narcotic

Is kind of interesting; one definition of narcotic is

> a drug (such as opium or morphine) that in moderate doses dulls the senses, relieves pain, and induces profound sleep but in excessive doses causes stupor, coma, or convulsions

https://www.merriam-webster.com/dictionary/narcotic

So we can see some element of losing time in that type of drug. I guess? Maybe I’m anthropomorphizing a bit.

Does the system you’re querying ‘get it’? From the answers it doesn’t seem to understand these words or their relations. Once in a while it’ll hit on something that seems to make sense.
