How efficient it actually is? I laugh much less than I would like to. I do have adequate sense of humour and can find jokes funny but that's just a thought, I hardly ever laugh actually. Can the gas help me?
I was pretty much an addict of it, and it did make me laugh just a couple of times. That is not the main appeal.
What is the main appeal?
It feels quite trippy and delirious and somewhat physically pleasurable and if you have enough you teleport into another dimension
A humble amount of Salvia Divinorum smoked will catapult you to the orbit of the multiverse beyond all the dimensions you could ever imagine in an instant then gently land you completely back to Earth in just some minutes safely. This is not really pleasurable (that's why its abuse potential is low - I doubt many people would want to repeat the trip shortly after) but definitely impressing while free of any discomfort and physically safe.
