No, but plenty of people in various mental states have bought drugs and gotten friends or family members hooked, which eventually resulted in death.

I don’t agree with counting homicides and suicides together as “gun deaths.” But since many people do: there are about 40,000 gun deaths each year. There are 100,000 drug overdose deaths a year now, which is the result both of people’s own decisions about themselves, and people giving or selling drugs to others to get them addicted.
