In general I agree with what you say, Cyracuz. As Aristotle put it, "Everything in moderation." But there are some people for whom this "moderation" quickly becomes a serious problem. It did so for me, not in terms of illegal so-called "recreational" drugs but quite legal alcoholic beverages. I started drinking "in moderation" at a quite early age (early adolscence) and progressed through all the stages to full-blown alcoholic, unable to go through a morning, let alone an entire day, without a glass of something
alcoholic. I am now a member of Alcoholic Anonymous and have not had a drink in over 16 years. There are others like me on this site; they know who they are.
As for drugs and/or alcohol enhancing certain mental faculties e.g. the imagination, of course they do. But, for me, so do nature walks. I'm fortunate to be living on the island of Hawaii where I can walk around the rim of the main caldera of the most active volcano on this planet and be absolutely awed bby it. I can sit at the seashore and watch the big waves of the Pacific Ocean come pounding onto the littoral and, again, be awed by the power and majesty of nature in the raw. But, of course, I used to get similar stimulii on the mainland, treading through the pine woods of New Hampshire, looking for moose spoor (and sighting the occasional moose) or, on a clear day, climbbing to the summit of Mount Monadnock and knowing that from this pinnacle I am observing portions of three different states.
See, my concern for the OP here is that if he/she is feeling the need to talk about one's attitude toward drugs, there must bbe some deep-down misgiving which seeks justification and public approval. If everything was alright -- and "in moderation" -- there would be scant need to discuss it on a public forum. I would suggest he/she step away from drug use completely for a while and see whether -- and how -- this might change one's perception of both "reality" and "imagination."
