嗨
“hi / high”
嗨 (hāi) can mean "hi," "hyped," or "high" in Chinese slang. In party or drug-adjacent contexts, it points to an excited or altered state rather than a simple greeting.
A sound used for greeting, transliterating "hi," or describing excitement and a lively mood.
In party and drug-adjacent contexts, 嗨 can mean high, hyped, or in an altered euphoric state. It is broader than a single substance and often depends on the social scene around it.
嗨 is useful because it sits on the border between harmless and taboo. It can be a greeting. It can mean a party is lively. It can also imply someone is high. The character alone is not enough; the situation decides the meaning.
For learners, this is a register trap. A dictionary may give you "hi" or "hey." A club context, a police-news context, or a conversation about substances can push it toward "high." That ambiguity is why the word shows up naturally in a taboo slang cluster.
Unlike 叶子 or 白粉, 嗨 is not tied to one substance. It is a mood/state word. That makes it useful as an internal bridge from drug-coded terms to broader internet and nightlife language.

Explaining why a sentence feels darker than a greeting
这个语境里的嗨不是打招呼，是说状态不太正常。
"The 嗨 in this context is not a greeting; it means the person's state is not quite normal."
It can. 嗨 (hāi) can be a greeting like "hi," a word for being hyped, or a slangy way to describe being high. Context decides which meaning is active.
No. Most uses are harmless: greetings, parties, concerts, and excitement. It becomes drug-adjacent only when the surrounding context points that way.
嗨 borrows the sound and some feeling of English "high," but it is broader in Chinese. It can mean excited, lively, party-hyped, or chemically high depending on context.
