I wouldn't honestly be too worried about submitting drugs to the factory (We created a new consumables template with not just food and pharmaceuticals, but toxins, etc in mind as well, after all.)
As for the usage? Just be tactful. It's one thing to elude to the usage, give a generalization, 'character x was having difficulty accessing the terminal due to his recent high on drug x' but not something graphic or overwhelmingly descriptive.
