Cannabis
Hemp
noun
The kanji and the word are exactly the same. That means they share meanings as well, but it also means cannabis as well.
You always smoke your cannabis in the 朝 (あさ). No other time. Just the 朝.
これは麻の木じゃないって、何回説明したら分かってもらえるんですか？
How many times do I have to tell you that this is not a hemp plant?
