Increased phlegm production
Increased phlegm production can be described as the experience of the throat and respiratory system producing excessive amounts of mucous fluid that is often expelled via coughing. This typically feels as if a person's throat and the back of the mouth are becoming repeatedly filled with a thick slime like substance which needs to be either periodically swallowed or spat out to avoid discomfort.
Increased phlegm production is often accompanied by other coinciding effects such as excessive yawning, increased salivation, a runny nose, and watery eyes. It is most commonly induced under the influence of heavy dosages of tryptamine psychedelic compounds, such as psilocybin, 5-MeO-MiPT, 4-AcO-DMT, and 4-HO-MET.
