I agree. This is discussed in great detail in an article on the United Recovery Project website — https://unitedrecoveryproject.com/rehab-blog/high-eyes/ It explains that “high eyes” are not just an external sign, but an important marker of an altered state of a person, most often caused by cannabis use. It is especially important to pay attention if red eyes are accompanied by other symptoms: slowed reactions, strange behavior, or speech difficulties. The article also gives advice on how to support a loved one if you suspect drug use, and urges not to be shy about seeking help. This is a useful read for anyone who wants to recognize the signs of addiction in time or simply better understand what is happening to others.
