Dear @Shiva,
Curiosities are results of inclinations. I wonder if your’s is really a targeted quarry. If not then what is the fun of going to back streets where lights are dim and chances to skid.
Just for your updation, as per my understanding, DMT is a forbidden drug and it produces hallucinogenic effects, categorized similar to LSD effects. As you say it is called ‘sacred’ because, extracted from the plants, this chemical was used to give an "out of the world experience" effect which many god-men still do to deceive common devotees.
As the divine has endowed all human bodies with all the required chemicals within, some of them are mystical. You are right, that our pineal gland does secrete this chemical which projects vision during a meditative depth. But this situation could well be acquired by requesting VK of a session of meditation.
In my opinion, VK should not be requested with a banned drug effect.
