Get a Pipe-style vape
There are vapes designed to look like pipes, which avoids all your issues with smoking tobacco. You can use 0% Nicotine juice and don't actually inhale. For some reason, Amazon is allergic to listing them, though regular vapes and supplies are all over the place. You can use 0% nicotine juice to avoid all the bad health effects of nicotine.
A bottle of vape juice that has 0% nicotine sitting on my desk.
Here is an amazon search for 0% (nicotine) Vape Juice
Here are some links to potential vape-pipes:

Health and Safety Note: Nothing foreign you inhale is entirely healthy, even a prescribed inhaler does some damage to the lungs. However, ejuice and vaping is concretely shown to be safer than smoking, even though it does have its own problems. However, secondhand smoke is also a safety concern, and if that was prohibitive, then OP would not be attending at all.
My own experience, being someone allergic to actual cigarette smoke (I lose feeling in my lips, my eyes burn and eventually cough up blood) is that vapor from ecigs and vapes is vastly better and it doesn't noticeably bother me. I even use my own vape w no issue.
For a less anecdotal answer, here is an excerpt from a webmd article on vaping. The article does cite health concerns, but like most official sites, they're allergic to doing a side-by-side comparison of vapes vs cigarettes, and they mostly focus on the cheap, convenience store varieties, due to the fact that these are less healthy and it makes a scarier story.

WebMD - Is Vaping Bad For You?
E-cigarettes aren't thought of as 100% safe, but most experts think
they're less dangerous than cigarettes, says Neal Benowitz, MD, a
nicotine researcher at the University of California at San Francisco.
Cigarette smoking kills almost half a million people a year in the
United States. Most of the harm comes from the thousands of chemicals
that are burned and inhaled in the smoke, he explains.
E-cigs don't burn, so people aren't as exposed to those toxins. A 2015
expert review from Public Health England estimated e-cigs are 95% less
harmful than the real thing.
