中毒
"中毒" means "poisoning" or "addiction."
The word '中毒' here means 'addiction' and is used figuratively to describe someone's strong attachment or obsession to something, specifically the game in this sentence.
彼はそのゲームに中毒になっている。
He is addicted to that game.
Here, '中毒' refers to 'poisoning' in a literal medical sense, illustrating harmful effects caused by toxic substances.
毒を摂取した結果、中毒を引き起こしました。
As a result of ingesting poison, it caused poisoning.
In this instance, '中毒' again signifies addiction, particularly toward sweet items, emphasizing a habitual desire or craving for them.
