I'm not necessarily a huge fan. However, drug cartels are by definition terrorist organizations.
There's now a synthetic narcotic that is ten times more powerful than even fentanyl. Reports are that often 2-3 doses of narcan are not enough to counter it, even to get people to a hospital.
I have a very close friend who had a son-in-law who became addicted after an injury and the attending pain killers. A fix laced with fentanyl killed him two years ago.
Laws will never prevent addicts from doing drugs. However, if we can prosecute people severely for crimes using weapons and vehicles, I figure that anyone caught distributing anything laced with fentanyl or the new synthetic could be prosecuted for attempted homicide with a deadly weapon.
