Quickest to solve all the clues is the winner

Welcome to Virchester Emergency Department.

There’s a patient in resus that I need you to see. It’s a young lass who’s taken something, or maybe she’s just had too much to drink. Either way, you need to solve the puzzles to find out what’s going on. Once you’ve completed the puzzles, enter the password to find the correct antidote in the drug cupboard.  

There’s plenty of other patients waiting to be seen, so you best get to it. I’ll be keeping an eye on how long it takes you.
