I am the exact opposite of the TS. I get crazy reactions from good stuff, ranging from insane hunger, severe paranoia, hysteric silliness, nonstop laughing, temporary retardation, philosophical enlightenment to the point that everything I say is something spectacular, even "yes" and "no", LSD-like hallucinating, and more.

Conversely, cheap weed doesn't do anything to me at all, even tho the people who smoke all the time are getting high from the same stuff.
