If I were in your lead's place, I'd keep a small dose laced on some sensitive areas as insurance. Like on the lock to his evidence or the handle of the circuit breaker. Places he'd know to avoid touching directly but a snooping thief or spy might blunder into as they snoop around posing as a client or cleaning crew. Turn them into horny little messes that can be collected and "pumped" for information on how they came to him.
As for myself, I'd probably keep to the original use and just motivate my partner a bit. Maybe lace a "health shake" to make losing weight a lot more pleasurable, since we both could use a little positive reinforcement these days (before she starts putting on weight for 9 months)
