How much is too much???

[KenRob316]

I apologize in advance if there is already a post about this but I tried sifting through and could not find it. If it exists please just slap me and refer me to the correct thread. Thanks!

Ok, I vape most flavors at 6mg/ml and can easily go through approximately 70-90ml in a week. Sometimes more when I drip heavily. While I rarely feel like I am od'ing on nicotine I am curious if I am exceeding the recommended daily allowance of PG/VG into my lungs. Any information is welcome and very much appreciated.

And before anyone suggests using higher nicotine level juices and cutting down on total amount that will not work. Any higher level almost always gives me a headache in three hits or less. So, if I am using far more than I should then I will just have to cut back and deal with it...lol

The simple answer is, at this point there is no "recommended daily allowance", as you put it, for any vapor ingredient.

There are some inhalable medicines that are based in PG, but the recommended dosages for them are primarily for the main ingredient, i.e. drug that's suspended in PG, not for the PG itself. I am not aware of any medicines that use glycerol as a solvent.

I say, if you're feeling ok, then that works honestly if I were you I'd be more concerned about how much money I'm shelling out for 90ml a week

If you're really concerned about it, you can try just taking it into your mouth and not inhaling, or inhaling less deeply, for some of your puffs. That will lessen the effect at least.

Wow I thought I vaped a lot (40mls week).

 

[KenRob316]

I figured this was the case. And I honestly feel great. Since I quit smoking cigarettes I have noticed all kinds of wonderful changes, not the least of which is my ability to climb the stairs to my apartment without having to take a break halfway up.

As for the cost, I have already made my first order of materials to DIY my own juice. Looking forward to experimenting and seeing what I can come up with!

Just to throw this out there. I watched a video of a guy who did a test over a month. He started at like 18 or 24 mg juice and every week he went down in mg and tracked his ml usage. He found that he vaped less juice over the course of the week at the higher mls. But he vaped a lot more at the lower end of range. He deduced that it was more economical for him to vape at a slightly higher mg then he was using or though the needed to be at. So in the end he was buying less juice over the course of the month.

This makes absolutely perfect sense. My issue is I started at 24mg as suggested by my vape store clerk due to the amount of cigarettes I was smoking. I quickly had to go down in strength due to nearly giving myself a heart attack and causing massive headaches. I am waiting for my first shipment of supplies to start trying the DIY thing and plan on attempting to make 12mg and 0mg of the same flavors. Alot of the time I just enjoy blowing clouds and trying to set off the smoke alarm. So I will be using the 0mg for that and when I need a fix going for my 12mg mix.

I now just need to sift through these forums until I can find some good threads on beginner DIY recipes and techniques.

I had the same thing happen to me. It was suggested i start at 18 but i quickly dipped down to 12 then i tried 6 and was burning through tanks of juice. I went back up to 12 and have been there ever since. I still feel like i am taking in less nic then when i smoked. I actually vape WAY more in my office at work than i do at home! Think stress has anything to do with that!?

I'm currently in the same-ish boat.

I mainly drip 3mg and go through anywhere from 30-50mL a week. As a member of Drip Club juice subscriptions, they send me mainly 3mg, but I also get in 6mg. I find that I have a hard time dripping 6mg due to the upgrade in throat hit. I normally vape higher VG blends, like inbetween 60/40 and 80/20 VG heavy.

I've also noticed that since I've started dripping, I have felt a little bit more labored breathing if I vape too much in a given period. It'll normally last for a few hours too. Never felt this way from cigarettes. I play soccer weekly and go to the gym twice a week and don't really notice the respiratory difficulties then; it's more noticeable when I am at work or just before going to bed, when I am sedentary. I tend to overthink things, but I already know that it is most likely not the nicotine since I'm at the next step to 0mg (I do know that higher wattage nicotine delivery is much more efficient). I am presuming it is either too much VG and my lungs are getting congested, or a flavoring that is causing some sort of an allergic reaction (not to mention The Flavoring Which Shouldn't Be Named...Diacetyl). We really need to eliminate that stuff once and for all.

I'm 3 days away from 1 year vaping, but the past few months since I started dripping subohm, I haven't been 100% happy with vaping. Bittersweet, to say the least. I feel as if I should go to the doctor and get a lung capacity test done, because although I love vaping, sometimes this small problem can be irritating and uncomfortable. I'd much rather look into it instead of let it go unchecked. As the majority says their lung capacity has improved since quitting the analogs, I'd love to hear if anyone else has experienced what I am or has felt this way.

VG makes my lungs feel like lead.... I avoid it completely. But, that's just me....

And getting your lungs checked is always a good idea!!! Good luck

I felt I was chainvaping 50ml a week of 0‰ nic of 30VG DIY NETs. Feeling all right tho with a mild sore throat some days. When I get that I put the gear away and grab a cup of coffee/tea/beer/whatever...

I worry about this too

I exp the same since moving up to higher vg. I usually vape from 70/30-90/10 vg pg . I was considering going up in pg to see what the diff is. I didnt exp it before but I wasnt dripping . Maybe a little science exp on myself . Ive read high vg can do this and Ive read things about pg as well. I pretty much abandoned tanks when started dripping so now Im going to revive my kayfun and use that most of the day with the same juice Ive been using see what happens. Im going to assume it will change. Kayfun is modified for more airflow but its nothing in comp to what I get from dripping. I go through almost 90mls a week sometimes more. I dont think that will change but Im figuring the high vg with the amount of vapor produced causes the little breathing problems esp if you constantly drip. Ill post an update in a week.

........ I am not aware of any medicines that use glycerol as a solvent.

That was basically true a few years back, but no longer holds. Some of the big pharmaceutical firms are shifting from all-PG for their inhalers (e.g. asthma inhalers) to a PG-glycerine mix, or all-glycerine. The reason may be two-part:

- For new users of their inhaler, there is the same risk of dry throat / sore throat as for new vapers. PG can cause that in some people. We know that passes for most people, in time, but it looks as if pharma doesn't want to have that issue at all. Also, for maybe 1 or 2 in 100, it can be a fiercely sore throat, as we know. They probably want to avoid that.
- They may know more than we do about the long-term effects of PG inhalation. People have been using asthma inhalers for decades, and they are (or were) mostly PG-based, like most ecig refills. There could be a problem we don't know about yet.

You can see how pharma suppliers treat this by looking at Dow Optim web resources. Optim is a synthetic glycerine* that Dow make. They produce pharmaceutical grades of PG and glycerine for inhalation, and now advise manufacturers to use Optim (synthetic glycerol of pharmaceutical grade) instead of PG, for inhalators etc.


* We call the stuff we use VG but it is debatable how accurate that is. It can be called glycerine, although the best 'popular' name is glycerol as it is the most accurate, because it shows it is an alcohol, like the glycols (PG for example, propylene glycol). Something with an -ol suffix belongs to the alcohol family (and is therefore not an oil).

The full chemical name for glycerol (or one of them) is:
propane 2,3, triol

...and for propylene glycol is:
propane 1,2, diol

So in a manner of speaking, we vape propane. Just don't try and light up your ecig Only joking.

I'd be curious if this still happens when vaping at lower temp/voltage? There was that study that showed carbonyls appearing at "higher voltages," although it was still pretty preliminary.
