Well for those bubble heads, advocating that every man, woman, and child in Britain should be allowed to experiment with every recreational drug going, judging from what we've seen in this thread, they don't seem especially happy little space cadets.
I can only suggest, to be truly happy little bunnies, you need to up your intake, or change your dealer.
If I ever find I'm so desperately sad with my life, I'll actually change it in reality.
Rather than temporarily alter it chemically.
For those that do don't seem particularly stable, happy, or content.
