I personally have smoked DMT over 10 times and I have also done LSD, none of those experiences compare to the rush I get right before I project though. Yeah doing these drugs definitely feels good but that only lasts for a limited amount of time and I personally dread the comedown effects. Also, just as you can have a bad experience while you project they can happen under the influence of psychedelics and nothing is more terrifying than having to sit through a bad trip until the experience is over; with astral projection you will end up waking up and that's the end of it. I personally don't think doing drugs is the ideal way to reach those states of consciousness but it is a way. DMT is a very powerful drug and it isn't something I would do just because it feels good.
