Diluting IV narcotics = narcotics tampering?

[mcknis]

I was told the other day that it is now illegal, yes illegal, to dilute IV narcotics because it means that we are now 'tampering' with narcotics. What do you think? We have now been told that ALL narcs must be given via Carpujects and can not be diluted. What is your policy?

If this were truly the law, it would be illegal to then make narcotic infusions, wouldn't it?
