Complelty silly but I spent allot of time going through Gas chambers, I started volunteering when I was in Korea and learned to piggy back off different units schedule chamber time. It bugged me that the gas had such a strong effect on me so I would spend as much time in the chamber unmasked as possible....then it became a drill of how effective I could move in the small space while under the effect.....to be completely honest the stuff effected me just the same as on the first day, no matter the exposure. But I got efficient under the exposure and could last upwards of multiple min within the chamber while still being able to field strip and M-16/SAW.......always wished I could have fired live rounds at targets while under the effect .....actually came to enjoy going to the chamber...In about 6 years I entered upwards of a hundred times, while most of my peers and soldiers would enter just once or twice a year.

100 exposures over 6 years ( 2160 days)  so needing a CS gas 'hit' every 21.6 days.

Congratulations, you are somewhere between Mild and Moderate Addiction: Tear Gas

Moderate with the occasional withdrawal effects.

Yup, that's it, the Original RAW Respirator.

Some yuppie hoods could even go this route during Flu Seasons.

The Neo-Anarchists Guide to Real Life p. 74 Fellini-Med Breather
This new particulate matter filter cleans the air you breathe using electronic precipiation, and the new-for-'52 Fillini-Med products. The new model has a lower profile, and its more flexible material softly cups the mouth. A gentle clip of patented SoftTouch(tm) holds the nose closed. Completely self-contained, the Fillini-Med Breather dispenses with intrusive, gugly battery packs. A single 4mm Geltech(tm) energy cell powers the Breather for up to 60 days of continuous use.
The Fellini-Med Breather clips neatly onto the lapels of today's high-collar jackets, and comes in a wide range of designer colors and textures.
(Fellini-Med Breathers start at just 350¥, including one Geltech energy cell and two replacement filters. Additional filters cost 45¥ each.)

The gas mask is always useful. I remember being in a situation were our team had to recover a black box from a downed drone in an dump that housed ghouls. The stench of rotten flesh in the air was so bad that if you didn't have a gas mask, you were taking penalties or making composure tests. Our Troll Adept Tank who thought he was cool ended up being useless in combat because he was too busy vomiting all over the place.

While this does make sense that contact/inhalation vector toxins do affect both skin and lungs simultaneously, I would houserule that if you ran into a dual vector gas, a gas mask wouldn't provide immunity but halve the power. 
It's not completely negating the effect because there's still contact, but it's reducing it as you're not breathing it.

[Novocrane]

I ditched the hassle of dual vectors, and simply use them as a guide to which delivery systems can be used with what.

Gas grenade? Inhalation vector. Capsule rounds / Super Squirt? Contact vector. Injection darts? Injection vector.

(plus some edge cases like a sealed room with a gas grenade, or a clip of broken darts)

[MijRai]

My personal take on dual-vectors is that you have to have protection from both agents, otherwise you get hit with the whole she-bang.  This is mostly due to my CBRN experience, where I know a couple drops of a nerve agent on your hand can kill you in minutes, much less breathing it in.  That said, I think the vectors are a little messed up.  CS on your body ain't going to do jack nor shite if you've ever had chicken pox.  Breathing it in or getting it in your eyes is another matter (also a good way to clear out your sinuses when you're sick). 

[The Wyrm Ouroboros]

My personal take on it is that there's two sorts of 'contact' vector - there's direct contact (i.e. the couple drops of nerve agent on your hand) and indirect contact (such as an aersolized something-or-other - gas grenade, where it's essentially microdrops, and thus microamounts).  Any sort of agent that's designed for standard two-drops-on-his-forehead-and-dead-in-the-morning direct contact will, when aersolized, make you pretty sick - after you spend five or ten minutes in it, and the amounts, microscopic in comparison to the 'standard' amount, finally build up to a dosage level that matters.  If it's DESIGNED to be aersolized skin-contact nasty, then you're screwed, and breathing it in is going to screw you over harder and faster.

[Dr. Meatgrinder]

I don't know if they still do it but anyone who went through Army basic at through the 80's can tell you exactly what it is like (at least for CS gas.)  For me the effect on skin was minimal, the effect on eyes was about the same as getting some smoke from the BBQ in the face but the affect on the lungs was pretty extreme.  For me it was sucking in a lungful of water.  In reality the effect on a given person can vary considerably from person to person.

They were still doing it in the late 90s. I'm pretty sure they're still doing it now. My experience was similar. The skin contact wasn't really much more than an annoying tingle, although I would bet it might get worse over time. For me, the eyes was a pretty searing pain. Like you, the inhalation took the cake. I saw a few people vomit and a lot of people had, uh, CONSIDERABLE mucus generation once they cleared the chamber.

I deployed in 2008, and I went through the gas chamber as prep for that.  They made us stand there in our gas masks for a while to make sure we had a good seal, then they made us take off the masks to get a hit of the gas.  I don't really recall having any problems with just contact vector, except you don't want to rub your eyes until you've washed up.  Even standing there without a mask wasn't too bad until I actually took a breath of it.
