Safety
The safety of research chemicals is untested and little if any research has been done on the toxicology or pharmacology of most of these drugs. Few, if any, human or animal studies have been done. Many research compounds have produced unexpected side-effects and adverse incidents due to the lack of screening for off-target effects prior to marketing; both bromo-dragonfly and mephedrone seem to be capable of producing pronounced vasoconstriction under some circumstances, which has resulted in several deaths, although the mechanism remains unclear.

Famous quotes containing the word safety:
“He had a gentleman-like frankness in his behaviour, and as a great point of honour as a minister can have, especially a minister at the head of the treasury, where numberless sturdy and insatiable beggars of condition apply, who cannot all be gratified, nor all with safety be refused.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Once women begin to question the inevitability of their subordination and to reject the conventions formerly associated with it, they can no longer retreat to the safety of those conventions. The woman who rejects the stereotype of feminine weakness and dependence can no longer find much comfort in the cliché that all men are beasts. She has no choice except to believe, on the contrary, that men are human beings, and she finds it hard to forgive them when they act like animals.”
—Christopher Lasch (b. 1932)
“... what a family is without a steward, a ship without a pilot, a flock without a shepherd, a body without a head, the same, I think, is a kingdom without the health and safety of a good monarch.”
—Elizabeth I (1533–1603)
