Tips

usage
The most common collocations are 上瘾 (to become addicted) and 过瘾 (to satisfy a craving / to have a great time). 上瘾 can be serious or casual; 过瘾 is usually positive and colloquial.
memory
The radical (sickness) plus (hidden) - an addiction is a hidden sickness.

Components

radical
sickness; ailment (radical)
Outer sickness radical (depicts a person leaning on a sickbed) - the indexing radical. Marks as a pathological condition. The same radical anchors disease vocabulary: (illness), (pain), (mad), (itch), (tired). Frames addiction as illness, not vice.
phonetic
yǐn
to hide; concealed (here phonetic)
Inner supplies the sound (yǐn - exact match) and a poetic semantic hint: addictions are hidden cravings, ailments concealed inside the person. Sickness + hidden = an illness lurking out of sight - neat compositional logic for both pieces.
