It took me 6 months to get a license to include a common opioid medication in my research line. I spent weeks as a detective investigating who might have a license that I could hook on to, going from one person to the next. I tried researchers, who couldn't help me, I tried the hospital pharmacy, couldn't help me, in the end I found a legal representative of the University who was licensed to apply for an addition on an existing license of the animal core facility.
In the end it would have been easier and faster to contact the vet at the animal core facility (like in Andy's post), if only I had known.. it would have saved 3 months in waiting (documents disappearing on the wrong desks).
A controlled substance must be locked in a safe, even with the license in place I need to apply for a 24-h expiring license in order to perform experiments. Try and find someone who is aware of the local legislation.
I'm now investigating the use of other medications, I'm afraid that will cost a lot of time again. Oh, and it is really expensive as well. A new license costs about 1500 euros, every time an order is made about 200 euros is charged for the "special treatment".
