Be careful if you do that with nicotine holding e-juice. It's easy to take in a much higher doses then you would with an e-cig, nicotine can be lethal in a high enough dose.
nicotine poisoning
Yes nicotine is a relatively poisonous alkaloid, thanks for pointing that out.
If you are mixing or dispensing liquids, you
must be able to estimate how much nicotine you are portioning-out and consuming. It can help to consider whether an intermediate result is actually a number that translates into a realistic real-world amount. In other words: If your calculations tell you to put a pound of sugar into your coffee cup,
don't believe the calculations.
Anyhow given the following:
* The e-liquid contains 10mg/ml nicotine
* One ml e-liquid contains 20 drops of e-liquid
* Quantity applied per 'bowl' is approximately 1/2 drop
can you calculate how many milligrams of nicotine is in the Arizer Solo stem?

Code:
0.5 drops * ( 1 ml / 20 drops ) * ( 10 mg / 1 ml )
Cancel-out the terms and multiply.
Code:
= ( 5 / 20 ) mg = 0.25 mg nicotine
That's 0.25 mg in the entire stem.
And that is inhaled over about ten draws
Code:
( 0.25 mg / stem ) * ( 1 stem / 10 draws) = 0.025 mg / draw
And only a fraction of that is absorbed by the lungs into the bloodstream -- the rest is exhaled in the vapor clouds. I don't know how much is absorbed into the bloodstream... 10, 20, 40%? For now let's just assume the bloodstream absorbs ALL the nicotine from the Arizer. That is, we are going to consider whether the worst, most dangerous conditions could lead to an overdose.
The estimated lethal human dosage (for at least 50% of those exposed) of nicotine is approximately 40-60 mg versus 0.025 mg in the stem.
Under these conditions, a normal lungfull from my Arizer Solo delivers about
two thousand times less than the published LD50 of nicotine in humans. This is good, because when we take medicines, we dont want to be within spitting distance of a lethal dose -- we want our dosage to be
Orders Of Magnitude smaller than the estimated lethal dose.
Knowing a published LD50 figure does not mean it is safe to consume any amount up to the LD50! Please don't try that.
Ran out of time, hope i remembered everything... cheers folks! fun forum!
[edit] Yet another thing to do with solo stems! Today I found an unused 30 watt soldering iron with ceramic tip: This, of course, had to be tried immediately...
A straight Solo stem was filled 1/2 with material and moderately packed, then a silicone tube was attached to the top (inside wall of stem). The entire tube and whip were placed on the exposed ceramic element to heat for about 1 minute.
Effects: Very smooth but powerful-hitting, a lot cooler smoke than the Solo, very little air resistance, a lot of debris in mouth (bad screen seating). Slight remnants of funky ceramic taste. Fun experiment, and required no modification to the iron.
Edit2: after vaporising a total of 8 stems to a medium tan, three trials resulted in combustion - American Spirit tobacco quick to burn. Further combustion was prevented by lifting the stem 1-2cm away from the end of the heating element. Next tubes will be longer for this..
Edit3: silicon tube is nearly ideal for cigarette filter: cut down in diameter, it gives a very nice taste, and flash! Smell of ceramic hard to notice at all now, after 4 hours of full temperature operation.
