Medicine
Drug, Drugs
noun
The kanji and the word are exactly the same. That means they share meanings as well. If you're looking for medicine in Japan, look for this sign.
Since this word is made up of a single kanji, it should use the kun'yomi reading. When learning the kanji, you didn't learn that reading, so here's a mnemonic to help you with this word: You need some medicine, stat! But, nobody wants to give you any medicine. You keep asking your pharmacist, Yuri, if he'll give you some medicine. He says no. You get pissed off, and you cuss yuri (くすり) out. He gives you the medicine after you cuss him out.
これは何の薬ですか？
What is this medicine for?
薬屋さんで薬をもらってきました。
I got the medicine at the pharmacy.
あの男は、薬づけの生活を送っている。
His life is loaded up with drugs.
