Sorry, no etymologies found.
6 A second dose administered within an hour will also cause less of an intense response. 12 For these reasons cocaine users will take the drug repeatedly every 30 to 40 minutes if available. 7 It has been reported that the craving for another dose after smoking freebase is more intense than after I.V. cocaine HCI and explains the high addiction potential of freebasing. 10
Some people who cross the line from powder cocaine to more hard-core use are into freebase, which is made by mixing a pure form of cocaine with ether.
Freebase cocaine is essentially pure cocaine that is made today by preparing an aqueous solution of cocaine HCI and adding ammonia or bicarbonate to alkalinize the solution and precipitate alkaloidal cocaine. 6 The "freebase" formed is nonwater-soluble, does not decompose. with heat and can be crushed, and mixed with tobacco and smoked.
By the early 1960s, however, Philip Morris had also begun using ammonia to "freebase" the nicotine in cigarette smoke, creating low-yield (reduced-tar or - nicotine) cigarettes that still had the nicotine kick necessary to keep customers "satisfied" (i.e., addicted).
"Have you ever used any form of cocaine, including powder, crack, or freebase?"
When cocaine is smoked as freebase and inhaled, delivering the cocaine rapidly to the pulmonary vascular bed, a rapid increase in blood concentration occurs with intense euphoric effects similar to that of rapid I.V. injection but lasting only 20 minutes. 6 In one study comparing smoking of freebase with I.V. cocaine HCI use, smoking 50 mg. of freebase (inhaling 16 mg. cocaine) caused a more pleasurable euphoria than 20 mg.
It has become more profitable to make freebase cocaine at home using kits sold for this purpose as the cost of cocaine HCI has dropped. 5
Use of cocaine, which now crosses all segments of society, has risen due to its increased availability, decreased cost, and more advantageous routes of administration through the use of freebase cocaine.
I've also been listing inspiring women at modernbluestocking. freebase.com, though as it's a much broader project, not everyone listed works with technology.
I went because it tied in really well with some work projects (like the museum metadata mashup competition we're running later in the year or the attempt to get a critical mass of vaguely compatible museum data available for re-use) and stuff I'm interested in personally (like modern bluestocking, my project for this summer - let me know if you want to help, or just add inspiring women to freebase).
