Suboxone can be abused and is highly addictive. It's an opiate paired with an opiate antagonist called Naloxone to reduce cravings. It's a maintenance medication to treat opiate dependency.
I believe one unnamed person in China was caught with $5 million or so; but $960,000 CAD was still missing; so maybe not? Even if they only walked away with 8% of the total originally 'stolen', that's still pretty damn good.
Plus, it would probably bring the heat off of you. The investigators and the university get to say 'we successfully recovered 92% of it!' because that makes a great headline where 'justice was served' and have the case take a lower priority.
