I quite agree - anybody caught doing this kind of thing should be punished. It is a most despicable thing to be involved in, and I am sure that these people don't give a thought to the repercussions and suffering of their families, addicts and all the victims of crime and poverty that surround the drugs trade.
Most of the people who suffer are the innocents (including the families of those caught). My thoughts are with all of these people.
The dealers, trafficers and producers all deserve what they get.
