Do you believe that drugs open your mind? Expand your ability to think?

Many drugs give people a different perspective of reality, I think that is always a good thing. But, moderation is always the key, but this applies to everything, not just drugs. People have died from water overdoses, you can die from exposure to high concentrations of oxygen etc. Everything is dangerous in excess, but I don't see why we should demonise a particular section of substances. In my mind the most devastating drug is legal in the majority of civilizations, alcohol.
