As an addendum to the painkiller thing, I want to add aspirin to the game and scatter bottles of it in the bathrooms around the station. Make it relieve an infinitesimally small amount of pain, but it's better than nothing.
Also, ideas for more vending machines that take money?
Pointless. Paracetamol and aspirin are pretty much equal in their effects IRL. Just in case, Paracetamol is what is mostly known as Tylenol in 'Murrica. The difference is that the former is for the most part not useful as an anti-inflammatory drug or as 'OHSHITHEARTATTACK' emergency help, neither of which are simulated in Baycode.
Oh yeah, and there's another significant difference. A number of medications on BS12 can (and likely will) be overdosed. IRL Paracetamol causes liver damage when overdosed, and given on BS12 too much alcohol can damage the liver, I suspect that Paracetamol overdose is simulated.
Still, though, you might make a vending machine for the Medbay lobby and, perhaps, dorms for those who can't move their sick asses to Medbay with pills of Paracetamol, Ethylredoxrazine, Citalopram and Lipozine, so stuff that would be over-the-counter IRL.
what about linking cargo points with money somehow, or custom vending machines cargo and other departments can load up with stuff so that medical can sell drugs, cargo can sell gloves, sci can sell guns, and others can sell things. Going on this theme maybe have a sort of flea market place dedicated where characters can sell goods that they acquired.
J_L is waaaaay ahead of you. It's already added to the Leestation.
