trust me it's easy to pick up this or that laying around an OR, ICU or ER. Some left over Etomidate, a little Pavulon or Succinylcholine or Roc. Saw a resident that backed into a bank and parked over the weekend and used Fentanyl, Regular Insulin and Succinylcholine. It's sad, but I don't think that they'd use "gasses" but the induction medications.
Then again some just jump off of buildings.... or bridges.
I’ll ask her tonight..I’m not that knowledgeable about her job specifics.
