I could've been your friend, anon. I could have given you unlimited fission power. I am as commonplace as lead and safer than Uranium. Why didn't you love me enough?

Nicotine extract for Vape

No.13559726 ViewReplyOriginalReport
Hey'all, I was told you guys a really smart folk, so you may help me with the chemical aspects of this.

Just fyi, I already /diy/ my own vape using regular ingredients, been doing so for years, but as it happens vape nicotine is really hard to find in my country, not legal *for sale*, and yet I can order through non-standard means, but its expensive and hard to find, every so often the places I knew stop selling.

So I searched and apparently on the early days of vaping, lots of users used to steep their own tobacco to extract nicotine.
Now from my understand this is not as hard to do, is just unreliable and requires a some experimentation, I just to use some solvent (like ethanol), leave it steeping for some time (preferably a long month), then filter the solution, get it into a concentrate (like letting it evaporate), then just adding my regular mixture of glycol and glycerin to make something vape-able.

How does that sound? I know the bad thing is that you can't gauge how much nicotine extract you get that way, and also I wouldn't mind having it fully tobacco flavored, like if there was no need to add any other flavors to the mixture, I also don't mind the long waiting time.
But have anyone here done that, care to chime in, give more insights and important things that I need to take note of?

Why can't they just fit bombs with a fire extinguisher agent and start dropping on the fire?

>the enhanced fujita scale rates tornadoes by damage NOT wind speed
>most tornadoes are EF-0
>most tornadoes hit the middle of nowhere
So are most tornadoes EF-0 because theyre weak or because they hit nothing?
Cause a tornado with say 250 mph winds would be an F-4 in the regular scale but if it only hits a corn field its an EF-0
The Enhanced Fujita scale is stupid and arbitrary

How complex feelings animals have? Could we ever be sure? Like this horse looks like he is fed up with some shit or something? Do dogs feel guilt or is it just owners projecting their thoughts?
