I was just going to say that drug trafficking and many of the offences we're talking about here are descriptive categories that engender in one's mind a particular offence, and usually a very serious one. But in fact it actually describes a huge range of behaviour, from circumstances that are relatively minor to very serious. It ranges in everything from two people who are sharing a joint to importing shiploads of heroin.
Again, I think that is the problem with using such arbitrary criteria, as opposed to good judgment, which can only be done on an individual basis.
