How do I get past Tuskin?

Hint 1 of 12:

Have you learned about the food dispenser yet?

Hint 2 of 12:

Try getting a box of food from it (use Kirk on it) and then use the box of
food on the medical table for an analysis.

Hint 3 of 12:

The food is drugged.

Hint 4 of 12:

Perhaps Tuskin needs some of that drugged food.  Deliver it to him.

Hint 5 of 12:

In the attempt, at least you'll learn that Tuskin only takes food from Moll.
