Quote from the original post's last paragraph:

" ... kundalini from using carbon dioxide which will travel up to the brain and cause a black out. This type of samadhi is a samadhi but it is one in the mode of stupor (jada samadhi)."

What could be the value of jada samadhi (given that it is still a samadhi)?

Because it is accessed or created from an admixture with carbon dioxide it yields a lower grade experience with less clarity and can have a duller and heavier feel in texture.

It can happen whenever the ratio of carbon dioxide to oxygen is skewed in favor of the apana because of the lackadaisical and instinctive behavior of the lungs towards breathing and/or the yogin level of proficiency. 

Still, it is a good opportunity to observe internally for the self. It still participates in the long term familiarity with the different levels of consciousness. Because the path be considered a continuum, it calls for patience and full reconciliation with the endeavor.
