A burning question

Question part 2:
What drug was the graphic artist on when he did the Mind's I booklet?
 
i think the hardest drug niklas has ever taken was that one time he dared add milk in his tea.

as for booklet interpretations, there was a thread a long long time ago. i think ormir had good ideas on the subject.
 
How dare Niklas add milk to his tea!

I'm outraged! :)
