BZzzzzzt! [Pun intended]

Now, don't get me wrong.

I typically enjoy "Uncle Al's" posts.  In fact,
I search them out.  

I'll continue to.

That being said, however, I have noted his 
disturbing tendency to sensationalize, exaggerate, 
and hype -- not to mention his usually simplistic, 
superficial, and rather inane political ramblings.

What I've also noted is that whenever I happen to
know something about a subject he's hyping,
his facts and analytical skills seem to frequently
go gurgling straight down the intellectual toilet.


I could go on, but interesting posts being things
that should be encouraged, especially considering
the rather pallid shadow of what it used to be that
Usenet has become, I think I should stop here.


BZ has has estimated I.V. LD50 of .5 - 3 mg/kg in 
humans.  That's around 40 - 225mg for the average
man.  Looking at the mult-species data, I'd say
the lower limit is conservative.

LD25 would be not much lower, say, 75%.

Orally -- which is the area of relevance -- 
would be far higher (possibly 3 - 8 times
higher, once again comparing with multi-species 
LD1 & LD50 data).

On a lark, I compared the mass delta between a 
[small] stamp with glue, and one without and got 
.2 grains = 13 mg.


[A drum roll, please...]:

You wouldn't be able to get even 10% of the amount
necessary to kill on the stamp, absent an allergic 

And the above analysis doesn't even factor in things 

1. people don't lick all the glue off
2. it wouldn't be 100% BZ (there'd be
   some glue in the .2 grains)
3. many people use water rather than their
4. postal meters

Including other things like the probable
foul taste, and how much people write (and
in North America -- as Al might say -- whether 
they can write at all), I'd have to say that 
this is a gross exaggeration with numbers 
plugged in for [cheap] effect.

Re-checked and verified that your figure is off
by two to three orders of magnitude.  

Rosenblatt is a Fort Detrick document -- can't 
get more "Official Truth" than that.  Cross-checked 
with two other DoD docs. 

Your dosage figure is in line with the _minimum_ 
dose at which BZ's anticholinergic effects begin 
to manifest themselves.

Now, don't start back-peddling on me, Al.  100,000

Your turn.  ;^)

I've never heard of BZ being available illictly.

Benactyzine made a brief appearance, along
with JB-series glycollate esters such as Ditran, 
during the "exploratory" years of the late '60s in 
California as DMZ and TWA.

[Refs.:  "Love Needs Care" Smith & Luce (1970)
         "Electric Kool-Aid Acid Test", Wolfe
          (1981)                              ]

However like all such atropine-like compounds,
the effect is mainly of an unpleasant, deleriant 
nature:  mydriasis, dry mouth and hot, dry skin, 
and true hallucinations (unlike psychedelics, where
you realize that what you're seeing is a drug effect),
frequently coupled with amnesia.

The post-experience amnesia is probably a good
thing considering the frequently nightmarish 
nature of the hallucinations.

Most notable is the absence of the euphoria that 
makes indole-ring psychedelics pleasurable, and, 
indeed, eminently more marketable.

Anticholinergics are thus the proverbial "trip to
nowhere", and are generally of interest only
to those nitwits who equate the word "hallucination"
to something pleasurable.  A _bona fide_ example
of a little knowledge being a dangerous thing.

And further to Uncle Al's rather loose comments, the 
precursors to BZ are certainly available for < US$1k 
/kg, however 3-quinuclindinol is noted as a CW agent 
precursor under the Chemical Weapons Convention with
concommitant sale, export, and import controls.  

Good luck being able to actually _buy_ some, and start
polishing up on your "Leavenworth Lambada".

Of course, the CWC was recently voted down by the
U.S. Senate, in spite of chemical lobby support, but
this is one case in which suppliers are assuredly
proactive in reporting sales.

Now, you'd think Al could use the CWC as grist for 
his Cassandra mill, instead of his stock, alarmist 

But -- alas -- no....
