Oops... Erin, I like your writing, but this piece is really, really bad. Don't talk about what you don't know, mmmkay?
Starting with
When you take drugs to have a spiritual experience you are not having the experience... your post is full of unfounded claims, that, in my experience,
are not true at all.
Certainly, these substances are not for everybody, but I myself have learned a lot of very valuable lessons in my trips on psilocybe mushrooms, plus had experiences that left me in total awe for the greatness of nature, the beauty of it all. These experiences really don't leave you with nothing after the chemicals stop working... quite the opposite!
For me, mind expanding substances are a part of my spiritual life. I also practice meditation. Mind expanding substances are not physically addictive at all, and almost never mentally addictive.
I think Mato Kinze made a good point saying that it's all about intention. DayInTheLife also says some very good things. Experiencing ego death and becoming one with the all is... wow, one of the most beautiful experiences I had and certainly not one that lowered my vibration. I don't know where that was coming from Erin, but I suggest you really do some better research before writing anything like that again.
A lot of false claims being made in this blogpost... really a shame. As for the question "Are drugs a good way to achieve spiritual experiences?", I'd say: there is no good or bad, it's just a
different way, that may or may not lead to a different experience. It may suit one better than the other.
