Good point, Gandalf... You're a smart wizard By chemical reactions, I did not mean entire new sets of chemicals being delivered, I should have specified the whole process of seretonin reuptake blockers, dopamine receptor signaling with D1 and D2 receptors with satiety, stuff like that, but I didn't think anyone save a few members could understand that stuff stoned :P

Beachguy- I repsect your view on this particular topic, however, note that I used the term "know the limits" in my original post; I enjoy SAFE recreational substances that have very low if not nonexistent rates of overdoses- for what it's worth, I will never use the Big Four (I'm pretty sure most of you know what I'm talking about), as well as prescription drugs recreationally. The substances I choose to use are non-addictive, non-lethal, and have not shown any significant effects from long-term use- at any rate, these substances are not being taken multiple times in a reasonably short period of time.

If someone else chooses to use substances that are very addictive and damaging to the body, that is their discretion; although I do not condone it, I realize people will make their own decisions regarding what they choose to take or not to take.

I suggest checking out Timothy Leary's manual on Info-Psychology if you're more interested in psychological impact of technology on humans. It's an excellent read.
