i think the point being made is that people that over indulge in drugs, alcohol, etc. can cause endless problems. was it the drugs or the people that abused the drugs?
similarly, guns don't kill people. people kill people. but, it's a hard sell to get people to accept the reality of these truths. city people tend to believe that guns kill people. and then they'll point to the gun in the killer's hand as living proof of their contention. so, the story goes on.
