Yes, there is still a connection between drug trafficking and firearms possession or trafficking. We must remember that the more money or drugs people have, the more protection they need. We've been seeing this recently with drug theft. People want to protect themselves, they don't want to be attacked, so they carry guns. People also use guns for intimidation and to protect their territory, of course.
As I was also saying, you must remember that they use the same routes. So, yes, there is still a connection between drug trafficking and firearms possession.
