The slang term "faded" doesn't necessarily refer to a mental state induced by psychoactive drugs, such as the common
one used among college students,
cannabis. It can also refer to a mental state that one is in naturally, brought about by the company
one keeps.
For example, one can use the term faded interchangeably with the idiom 'on cloud nine,' as in the sentence, "Oh man, being with these people after such a long
time makes me feel
like I'm on cloud nine" or "
Bro, I was so faded just by chillin with those cool cats after so long"
