A "trip" in Chinese

Is there some kind of word in (Mandarin) Chinese synonymous to the English slang word "trip"? As in, a drug trip? I just tried up looking "trip" but it gave back the normal meanings for trip, such as a journey. I was wondering if the Chinese have a word that means something similar to the English slang? Or would it be happenchance they just decided to use the formal meaning of "trip" too?

Pinyin please, and simplified or traditional (unless it only has one, then that doesn't really matter which one you choose.)
