Raking a fistful of pill fail often, with little consequences (unlike a bullet, who might fail but consequences are painful).

Jumping is rare, the only case I know of was someone with bone cancer who suffered a lot (I'm kinda remember her but I was very young when she died). Bullets are a common way to go for people with hunting background. There is a reason why 'revolving credits' were called 'revolver credits' in my area before they were basically outlawed (I'm from the countryside).

People do kill themselves with guns, nobody was debating that...
