Pattern: 对 [thing] 有瘾 = 'be addicted to [thing]'. Used both literally (drugs, smoking) and lightly (games, social media, TV shows). Related expressions: 上瘾 ('to become addicted'), 戒瘾 ('to quit an addiction').
memory
有 'have' + 瘾 'addiction/craving' literally 'have an addiction'. The character 瘾 has the 疒 (sickness) radical because traditionally addiction was framed as a disease.
