HA HA... did you try it?
In the past two years I bet I have taken more drug tests for my employment than you have in in the past 10 years :) I don't dare eat a poppyseed roll....:) (Needless to say I passed them all!)
I can however consume enough coffee to kill a medium sized blue whale... I can mainline espresso... But coffee has yet to be a banned substance...
I did find the game addictive.... did you try it?
It is a game that requires a lot of thought and intuition.... I loved it!
