What does "Stoned" mean?
Definition: If you haven't figured it out by now, being stoned is a euphoric sensation you experience following the consumption of cannabis. It is a result of the plant's many psychoactive components, though mainly THC. It is certainly possible to get uncomfortably stoned, but nobody has ever died from it.
