Anyone going to Wembley today? Can you tell me how strict the search was?

I'm heading to Wembley Stadium tomorrow for the Weeknd and have a couple of questions for anyone who's attending today:

1. How enhanced/strict was the security search on entry? Pat-downs, bag checks, the works - just trying to gauge what to expect so I'm not holding up the queue.
2. Can you bring cigarettes or vapes in? I know you can't smoke/vape inside the stadium itself (no re-entry either), but does security actually confiscate them at the gate, or are they fine as long as you don't use them?
3. Any tips on the fastest way out of the stadium afterward? I'm in the Golden Circle North. I've got a 00:05am bus to catch at Finchley Road and no backup plan if I miss it, so any advice would be a lifesaver.

Any other last-minute tips from people who went today would be much appreciated.
