Heavy Breathing

[Mr.Darcy]

i have asthma,and it has eased greatly since i gave up the fags,and started to exclusively vape last April...

however,ive had a some bad days lately where ive been very short of breath,and my inhaler hasnt been able to ease it much...which is unusual...

the one thing those days have in common was that they were days after id been vaping a homemade zero nic mixture of just glycerine and menthol crystals the night before...
i dont make it too strong,and i use the best possible glycerine and crystals...

ive vaped pure glycerine on and off for months now with no problems whatsoever...but the glycerine and menthol crystal mixture leaves me with a heavy feeling in my chest next morning-like when i smoked...and quite severe shortness of breath...

im not certain its not just coincidental...but i doubt it somehow...it happens every time...

has anyone else experienced this kind of thing from using this mixture,whether asthmatic or not?

I had chest pains and heavy breathing when I tried menthol liquid and I don't have asthma. At the time I put it down to recently quitting the fags. I was Googling about this today coincidentally and it appears that menthol crystals are levo-menthol which can be hazardous when inhaled.

levo - MENTHOL

There are plenty of other safety warnings for it around as well. Not sure if the chest pains I had were related but I've not had them with any other liquid apart from the menthol

Sounds like you'd better stop using menthol.

And I have my pack of Menthol Crystals here too.

[Mr.Darcy]

thats interesting Scrub...i wonder if many others have this problem with store bought menthol eliquid...

anyway,from my own experience the DIY menthol crystal thing is certainly not for me anyway...

naturally i have stopped using them...im not taking any chances...

im just curious to hear if this is common or not...

[scrubadub]

Yeah I'm curious too Darcy. From all the menthol talk that goes on here it would appear that many people have no problems with it. Maybe it's an allergic reaction although I've had no problems with Vicks in the past.

I've found out today that, aside from nicotine, the other ingredient in Nicorette inhalators is levo-menthol so it must be generally safe to inhale. Maybe it's the concentration of it when using crystals that's the problem.

I've been using menthol crystals for months now without issues. I do use a much milder mix now but my first mix was like smoking a Halls cough drop. Now I could feel that in my chest for a while after vaping but never really felt it was a problem.

Many various inhallation medications like Vicks etc. include levomenthol as their active ingredient.

Levomenthol has mild local anaesthetic, cooling and decongestant properties and is often included in cough and cold remedies to act as a decongestant. It is not fully understood how it produces its effect.

When I was doing article research, I read that the inhaler had menthol added to temper the incredibly harsh throat hit of nicotine. I have one of those (used) inhalers that I've taken apart and pried the core out, then soaked it in e-liquid and put it back. Not bad. But not a high enough nic hit.

Note to anyone trying this: Your exposed nicotine will maintain strength for only a day or less. Then you're sucking flavored air. Even the Big Pharma device I had says to use within 10 hours.
