I like to ponder the long term implications of humanities long term use of the many diverse chemicals we have invented and ingest regularly. I think it's a pretty scared proposition. Even if we've been studying a sugar substitute, anti-depressant, or artificial flavor for 70 years, that's still a drop in the bucket of time, and it doesn't tell us what these chemicals could be doing to our very DNA!!! Yes, just because we don't see the harmful effects of something now, doesn't mean we won't find them later. Some things you can only see WITH THE PASSAGE OF TIME. What if we are permanently altering, however subtly, our individual DNA, and the gene pool of all of humanity? Yeah, I'm just speculating, and some would call me an alarmist over reactionary, but the truth is NO ONE truly knows the LONG TERM EFFECTS. Only time will tell.
