Why has my vape juice gone black (Affnix banana ice)

[NovoNohomo]

I recently put affnix banana ice (20mg) in my smok novo 4. I had put in a new coil the night before.

However, it was less than 1000 hits before the whole juice and the coil went black, weirdly the amount of juice in the pod had also increased slightly since the last time I had checked it and it had been in my pocket the whole time. But despite all this it didn’t taste burnt.

At first I thought it was because of the sweetness of the juice, due to the sweeteners caramelising and causing it all to look black, but my friends tried the juice in their vapes and it wasn’t a problem.

I also knew it wasn’t burnt, it didn’t taste like it was and I had been hitting it at 20W open airflow for less than 1000 hits on new coils, which I had primed.

Does anyone know what the reason could be?

I think I found the problem.

I forgot to mention that the pod was slightly cracked at the top, but not leaking.

Because of this oxygen was able to get into the pod, leading to oxidisation of nicotine, turning the juice brown.

If this happens to you, replace the pod or find out how oxygen is getting in. Sunlight can also lead to photolysis and subsequent oxidisation.

Don’t hit the dark brown vape juice. The nicotine won’t work and it has dangerous chemicals instead.

 

[smacuser]

Some juices contain flavors that will turn dark as they age quicker than others, especially when in close proximity to a heat source.

A cracked pod will not instantly oxidize the nicotine, nor does dark juice have dangerous chemicals.

 

[NovoNohomo]

It’s not a problem with the juice, it’s either the coil or the pod.

I replaced both and it’s not happening anymore.

Another thing that I forgot to mention is that I wasn’t getting nicotine rushes anymore. I thought I had just built up a tolerance, but as soon as I switched the pod and coil and used the same juice I got rushes again.

To me, this suggests that the nicotine had chemically changed.

It didn’t instantly oxidise it just gradually got darker over time.

Oxidised nicotine is also not safe to vape.

Oxidised nicotine is also not safe to vape.

Any credible sources that prove this?

 

[NovoNohomo]

My bad, it is safe but the nicotine turns into cotinine, which still has cancerous effects but u don’t get any benefit so there’s no point.

It also tastes bad

If ur really desperate ig u cld still hit it.

 

[smacuser]

I believe continine is the byproduct of nicotine after it’s metabolized by your body’s system. It’s currently being studied as a treatment for depression, PTSD, schizophrenia, Alzheimer’s and Parkinson’s disease.

 

[UncLeJunkLe]

it is safe but the nicotine turns into cotinine

I don't think that nicotine "turns to cotinine" inside a vessel, like a bottle, tank or pod. It is metabolized to cotinine inside the body, hence why drug tests look for cotinine (and not nicotine) when "they" test you for tobacco usage. But I could be wrong.

you lost me

 

[NovoNohomo]

Nicotine does turn into cotinine when metabolised, however this is also due to oxidation (meaning loss of electrons in chem) which can also happen in the bottle.

Im not saying it’s deadly to vape, all I’m saying is that it is still harmful and there’s no point in doing it cause u don’t even get the nic rush.

Not touching this. But I'll keep reading. Kinda interesting.

Your diagram left something out. Yes, that is the pathway of the metabolism of nicotine to cotinine. But it can't get there by itself.

• Nicotine is metabolized primarily by the liver enzymes CYP2A6, UDP-glucuronosyltransfease (UGT), and flavin-containing monooxygenase (FMO).
  
• Nicotine is extensively metabolized to a number of metabolites (Fig. 3) by the liver. Six primary metabolites of nicotine have been identified. Quantitatively, the most important metabolite of nicotine in most mammalian species is the lactam derivative, cotinine. In humans, about 70–80% of nicotine is converted to cotinine. This transformation involves two steps. The first is mediated primarily by CYP2A6 to produce nicotine-Δ1′ (5′)-iminium ion, which is in equilibrium with 5′-hydroxynicotine. The second step is catalyzed by a cytoplasmic aldehyde oxidase.

I’m not sure that just any run-off-the-mill Bear Grylls vape meme is going to do. I might have to create a custom meme just for this thread.

Nicotine is photosensitive and will gradually turn brown when exposed to light or air.

Anyone who's vaped for any while knows that. It doesn't affect the potency, only perhaps the taste if brown enough. It's still nicotine, though and makes a great pesticide when no longer vapable. Pour it on anthills.
