Blitzed
From Wiki Weed
Blitzed is most likely a permutation of the word "blazed," although there is no traceable etymological connection. Someone probably was too high to know what they were saying when the phrase "blitzed" was first coined. It may refer to a heightened state of intoxication beyond what is typical, due to a particularly strong batch of weed that causes effects immediately upon inhalation. "Blitzed" calls to mind the "blitzkrieg" of WWII and "blitzing" in American football terminology.
