Mate, the "security cheese" as you describe it has more holes in it than a colander! There are countless ways to get "items" onboard aircraft.
You can thank your lucky stars that most "items" smuggled onto aircraft these days are in powder form and are for human consumption.
It really isn't that suspicious for people to "fall sick" just after boarding an aircraft, disembarking sick (or other reason) people is just another day at the office. Even in the Dash-8 I personally do it around every 3-6 months.
DIVOSH!
