I would not equate the use of DMT, or any other drug, to meditation. Meditation is an internal process to explore self awareness and to create a sense of peace in life. DMT and other drugs might elevate your senses for a short time but they do nothing to create a lasting self awareness of sense of peace in your life.
In fact, the use of drugs can cause more chaos in your life if you become dependent on them. Successful meditation takes practice to see the real benefits, but the benefits will be much more impactful and long lasting compared to the effects of forcing self awareness through an external force.
