- You’re using oil that is too thin
- You might be overheating the oil which causes it to become too viscous
If vaping nicotine, or even zero nicotine the usual case is we
do not vape oils. Oils can and will screw up a person's lungs if not used properly, and carry that risk even if used proper.
Oils might be best used in waxes for dabbing and heating that way. The wax gets heated to an oil base. You
do not vape the oil though. What you are vaping is the off product of the wax being melted down to oil.
For example I might like a mixture of thyme & basil in some olive oil based wax. I can vape these herbs, and or other agricultural products in an oil based wax. The essences coming into the wax from the plant, spice, what have you are what's vaped. Again, you
do not vape the oil.
If this method is done properly, yes, a lot of risk can be mitigated. Though it is best described still as "
at your own risk", as often it's the case of "stuff happens". Vaping was not actually intended originally for use as means to use sweet leafs (leeks, cabbage, beet greens, water cress, [insert your own variant]). Sure it may do well for that, recall though it was meant as means to get folks off cigarettes.
Using wax requires an entirely different kit set up too. If you're doing that, there's enough here to point you in a general direction using a search engine. Suffice it to say a standard
disposable vape pen
is not what you want to use.
What nicotine vapers use to vape is called, e-juice, ejuice, juice, liquid, base and we now even salts. So we got what we call freebase juice and salted juice. I myself use freebase juice at 18mg per ml nicotine, usually unflavored, but at times I sneak a squirt or two of flavor in.
