Good observation!
But ketamine has been around the club scene for well over ten years now...and still only a small percentage of what is being consumed at raves...ghb, is slowly becoming rampart in certain areas...but the chance for that becoming mainstream is slim to none! As ghb, has the notorious reputation of being used as a roofie otherwised known as a date rape drug....no one ever wants to be dosed with a substance that can easily put you in a coma. Their are handful of youtube videos of people literally shuddering on their couches or beds while being sedated on GHB! But in its perfect recreational dose, it has the enabling power of seduction to be called: liquid ecstasy! Ketamine will always be the second choice at a rave to give a certain highlight or synergistic foreplay to ecstasy!
