It was stated that similar effects can been felt with alcohol.
Funny thing is I say to people who take drugs that everyone is looking to feel good, to feel better, to feel at peace and happy within themselves.
The truth of this is that everyone is thus trying to be spiritual. Thus drugs give that momentary spiritual feeling, that high. But alas it's via a physical means. Heavy training, alcohol, drugs, all physical means of trying to feel spiritually well in self.
Irresponsibility. Just be your spiritual self and depend on nothing else. Ha, ha.
