I jarred myself once. I was betting $600 a game one pocket and was up $3000 and I took a break and swallowed a vicodin. It was four in the morning and I had been up all day and night and I was scared of the bet.
So I thought the Vicodin would ease the pain and calm me down.
Was I wrong or what. I came back to the game 30 minutes later and couldn't make a ball in the ocean.
I made every mistake possible to sell out short of raking the balls to my opponents pocket every game.
I can't say that I have ever been drugged by anyone else in a pool room or elsewhere but especially in poolrooms I don't accept drinks from strangers and I tend to keep my drink under my control.
Of course the real reason may be that I just don't bet enough for anyone to waste the drugs on me
