I'll back it up if you like. Just PM me. Of course LSD isn't endogenous to our brain but there are natural receptors that it binds to. I implied that cannabis and LSD have similar physical safety profiles, not that they are similar in intoxicating nature.
No actually you said:
Pharmacologically LSD is just as safe as cannabis.

n.
1. The science of drugs, including their composition, uses, and effects.
2. The characteristics or properties of a drug, especially those that make it medically effective.
pharma·co·logic (-k-ljk), pharma·co·logi·cal (--kl) adj.
pharma·co·logi·cal·ly adv.
pharma·colo·gist n.
Since Pharmacology includes studying the intoxicating effects. To say something is pharmacologically as safe as something else implies that they are similar. So either you're being false and misleading or you're throwing around words that you have no clue of their meaning.
Also why do you need to be PM'ed to share what you have that "backs up" what you are saying? I mean if it truely supports what you say then why not post it up? My guess is that it doesn't support what you are saying at all and that's why you don't post it. That or it does support it but obviously comes from an unreliable and biased source.
