psylence

I do not believe that drugs open anything other than your personal limits of perception. However, you must consider that you are tampering with your brain by doing this and that your brain is what allows you your perception in the first place. (not your mind.. as we are talking about a physical alteration of perception due to physical stimulus)

Also consider that the "trip" we experience when we take drugs is simply a means of returning to normal function. You can "trip" off of anything. The "drugs" we take which induce any effect must be taken at a high enough dose to do so. Otherwise they are no more special than a dose of any other substance. What I'm getting at is that our trip is simply a physical response and nothing more. Your brain reacts to these in different ways but your concioussness is only altered in a very temporary way. While it may seem as though you've opened a door or pathway to some place new - consider that your mind has been forced to let go of the stifling chafe of conventional thinking for long enough to consider broader possibilities. It's no more magical than that. The boundaries of our perception are limited more by language and other cultural influences than anything else.
