There is a way to measure this if I am.  And, of course, if you start blowing 
smoke again.

BTW, congrats on the days of real breathing.  I know you aren't up to tasting 
real food yet, much less smelling dog $hit from across the street, but you soon 
will be.  Hang in there.  In about a year you will be able to identify tobacco 
smoke coming from a passing car on the other side of I-10.  So little time, so 
much to sniff.

 §92.111 Smoke measurement system. 
(a) Schematic drawing. Figure B111-1 of this section is a schematic drawing of 
the optical system of the light extinction meter, as follows:

(b) Equipment. The following equipment shall be used in the system. 
(1) Adapter. The smokemeter optical unit may be mounted on a fixed or movable 
frame. The normal unrestricted shape of the exhaust plume shall not be modified 
by the adaptor, the meter, or any ventilation system used to remove the exhaust 
from the test site. Distortion due to the gaseous or particulate sample probes, 
or the exhaust duct is allowed subject to the provisions of §92.114. 
(2) Wind shielding. Tests shall not be conducted under excessively windy 
conditions. Winds are excessive if they disturb the size, shape, or location of 
the exhaust plume in the region where exhaust samples are drawn or where the 
smoke plume is measured. Tests may be conducted if wind shielding is placed 
adjacent to the exhaust plume to prevent bending, dispersion, or any other 
distortion of the exhaust plume as it passes through the optical unit. 
(3) Smokemeter, (light extinction meter). A continuously recording, full-flow 
light obscuration meter shall be used. 
(i) It is positioned as specified in paragraph (c) of this section, so that a 
built-in light beam traverses the exhaust smoke plume which issues from the 
duct. The light beam shall be at right angles to the axis of the plume, and in 
those cases were the exhaust is not circular at its discharge, the path of the 
light beam through the plume shall be along the longest axis of the exhaust 
stack which is not a diagonal of a rectangular exhaust stack. 
(ii) The light source shall be an incandescent lamp with a color temperature 
range of 2800K to 3250K, or a light source with a spectral peak between 550 and 
570 nanometers. 
(iii) The light output is collimated to a beam with a nominal diameter of 1.125 
inches and an angle of divergence within a 6 degree included angle. 
(iv) The light detector shall be a photocell or photodiode. If the light source 
is an incandescent lamp, the detector shall have a spectral response similar to 
the photopic curve of the human eye (a maximum response in the range of 550 to 
570 nanometers, to less than four percent of that maximum response below 430 
nanometers and above 680 nanometers). 
(v) A collimating tube with apertures equal to the beam diameter is attached to 
the detector to restrict the viewing angle of the detector to within a 16 
degree included angle. 
(vi) An amplified signal corresponding to the amount of light blocked is 
recorded continuously on a remote recorder. 
(vii) An air curtain across the light source and detector window assemblies may 
be used to minimize deposition of smoke particles on those surfaces provided 
that it does not measurably affect the opacity of the plume. 
(viii) The smokemeter consists of two units; an optical unit and a remote 
control unit. 
(ix) Light extinction meters employing substantially identical measurement 
principles and producing substantially equivalent results, but which employ 
other electronic and optical techniques may be used only after having been 
approved in advance by the Administrator. 
(4) Recorder. A continuous recorder, with variable chart speed over a minimal 
range of 1 to 20 cm per minute (or equivalent) and an automatic marker 
indicating 1-second intervals, continuously records the exhaust gas opacity and 
throttle position. 
(i) The recorder is equipped to indicate each of the throttle notch (test mode) 
positions. 
(ii) The recorder scale for opacity is linear and calibrated to read from 0 to 
100 percent opacity full scale. 
(iii) The opacity trace has a resolution within one percent opacity. 
(iv) The throttle position trace clearly indicates each throttle position. 
(5) The recorder used with the smokemeter shall be capable of full-scale 
deflection in 0.5 second or less. The smokemeter-recorder combination may be 
damped so that signals with a frequency higher than 10 cycles per second are 
attenuated. A separate low-pass electronic filter with the following 
performance characteristics may be installed between the smokemeter and the 
recorder to achieve the high-frequency attenuation: 
(i) Three decibel point: 10 cycles per second. 
(ii) Insertion loss: 0 ±0.5 decibel. 
(iii) Selectivity: 12 decibels down at 40 cycles per second minimum. 
(iv) Attenuation: 27 decibels down at 40 cycles per second minimum.. 
(6) Automatic data collection equipment may be used, provided it is capable of 
collecting data equivalent to or better than the data required by paragraphs 
(b)(4) and (5) of this section. 
(c)(1) Assembling equipment for locomotive testing. The optical unit of the 
smokemeter shall be mounted radially to the exhaust duct so that the 
measurement will be made at right angles to the axis of the exhaust plume. The 
distance from the optical centerline to the exhaust outlet shall be minimized; 
in all cases it shall be less than 10 feet. The maximum allowable distance of 
unducted space upstream of the optical centerline is 18 inches. The full flow 
of the exhaust stream shall be centered between the source and detector 
apertures (or windows and lenses) and on the axis of the light beam. 
(2) Assembling equipment for engine testing. The optical unit of the smokemeter 
shall be mounted radially to the exhaust duct so that the measurement will be 
made at right angles to the axis of the exhaust plume. The distance from the 
optical centerline to the exhaust outlet shall be less than 25 feet. The 
maximum allowable distance of unducted space upstream of the optical centerline 
is 18 inches. In-line smokemeters are allowed. The full flow of the exhaust 
stream shall be centered between the source and detector apertures (or windows 
and lenses) and on the axis of the light beam. 
(d) Power supply. Power shall be supplied to the control unit of the smokemeter 
in time to allow at least 15 minutes for stabilization prior to testing.

You sure you’re not blowing smoke???

That was a nightmare, Jay.  It was not a dream.
 
The next time that happens you should awaken and walk as nude as you were made 
through the neighborhood while shouting, "I want to live!  Stay away from my 
body!"
 
This is VERY important to successful recovery from these horrible things.
 
You must also donate your Tobacco Enema machine to Goodwill.

Ahhh---back in the day when being a doctor was fun! 24 days, no smokes. Oddly, 
dreamt that I tripped up and smoked 1 last night.

Always one to illuminate and diseminate, I thought the attached photo might 
encourage you in your pursuit of higher purpose and better health.
 
Perhaps you were attacking the problem from the wrong end..
