Making your own laced cigarettes

[Dr Zoidcrab]

I tried that with a salbutamol cigarette from a pack of pro puffs with slow metabolism and it wasn't enough to keep me from suffocating. It's also erratic as to when cigs transfer reagents sometimes going for long periods without any, and the heat given off is so minor it barely if at all affects the speed that space cools you.

With slow metabolism it's already possible to just take a large dose of something and have it last for extended periods without taking up the mask slot, which means you can also avoid breathing in anything from the air by having internals running at 0kpa.
