Good evening tryptamine-enthusiasts!
Those who indulge in this activity of ours via vaporisation are sometimes heard mentioning a feeling of being unable to breathe whilst in the early part of the experience.Those who have experienced mu agonist opiates/opioids I suspect are troubled less by this subjective sensation, having experienced respiratory depression willingly (and probably repeatedly).
Heres an interesting abstract to a paper which considers a possible role of the 5HT2a subtype of receptor in mediating respiratory drive in a gasping fashion.Its been shown that 5HT2a receptors in the human brainstem are pretty crucial to promoting respiratory drive in the presence of raised blood CO2 after a prolonged epileptic seizure and those on SSRIs tend to get less hypoxic after seizures, quite possibly through a resultant agonism at these receptors.

I hope this physiological explanation allows venturers to trust their brainstems wiring just a little more implicitly!

Gasping Activity In Vitro: A Rhythm Dependent on 5-HT2A Receptors
Many rhythmic behaviors are continuously modulated by endogenous peptides and amines, but whether neuromodulation is critical to the expression of a rhythmic behavior often remains unknown, particularly in mammals. Here, we address this issue in the respiratory network that was isolated in...
