the ultimate state of ecstasy or euphoria obtained through ingestion of illicit drug(s) or substance(s)- also known as a "peak." A certain concentration of drug ingested by an individual causes this state of critical mass. Beyond this point of critical mass, further drug intake does not result in increased euphoria or ecstasy.
You want another E? "Nah, I've reached critical mass."
