Cách sử dụng
The expression "what are you on?" is a casual way of asking someone if they are under the influence of drugs or alcohol. It is usually used in a humorous or sarcastic way between friends or acquaintances. However, it can also be seen as offensive or insensitive if the person being asked is actually struggling with addiction or substance abuse. It's important to use this expression in appropriate contexts and with people who you are comfortable joking around with.
