Fan Casting Descent into Addiction in Sort by Tropes

A character arc which depicts a particular character's decline into some form of self-destructive addiction. They may become addicted to a substance (alcohol, heroin, opioids etc.) or to a pattern of behaviour (gambling, porn and sex addiction etc.). In Speculative Fiction works, this can include a character becoming addicted to a Fantastic Drug or fantastic pattern of behaviour (such as a sorceror becoming addicted to the intoxicating effects of using magic, for example).
