Not to nitpick, but the cutting accuracy issue is with drugs that have a close effective and lethal dose. LSD's high potency has little to do with it.
Actually, at least in the case of MDMA, the adulterants are, in fact, the issue:
"Testing kits are needed because many pills sold on the illicit market as "ecstasy" are fake and do not actually contain MDMA. Fake pills often contain drugs more dangerous than MDMA, including dangerous drug combinations, or drugs that are especially dangerous when mixed with MDMA (as often happens if someone takes more than one pill in a night)." ----from http://www.dancesafe.org/testingkits/
"Working in such conditions requires that a person be able to check himself, evaluate his condition in relation to the crew and in relation to mission control and be able to correct himself," said Boris V. Marukov, the experiment's director and a former crew member on the International Space Station."
Translating Ice Cube lyrics from Russian is terribly complicated.
Such as refined sugar. It's amazing how hard it is to find a decent lunch in some places that isn't full of sugar. This bothers me because it did lead to a degenerative disease in me -- I'm diabetic.
A little clarity here about symptoms and causes: eating sugar doesn't contribute to diabetes; getting fat off eating sugar does. Conceivably, if I ate enough of the stuff to gain 40 pounds, brussel sprouts could cause diabetes as well (not to mention increasing my risk of major depression by a few orders of magnitude).
Interchangeable parts won't.
