Getting high on refers to a state of euphoria induced by the consumption of drugs or alcohol. However, it is essential to note that this state can have negative consequences, including addiction and harm to physical and mental health. The antonyms of getting high on, on the other hand, are related to the experience of living a sober, healthy life. These antonyms include maintaining sobriety, staying clear-headed, being responsible, and focused. These are desirable states to aim for, as they lead to a healthier, more fulfilling life that is free from the control of substances.
