For the most part, LSD doesn't cause true hallucinations -- it distorts things.
Then you probably haven't tried the stash government uses for its experiments...
Also, it should be noted, that LSD (much like most serotonin agonists) are highly variable in their effects depending on the dose. When at 1/10 of a "usual" dose it may be a stimulant, at 700+mcg it is an authentic hallucinogen.
In any case, I have seen people conversing with fairies and "tasting sounds". Ahh, good ol' uni days...
No offense, but you probably weren't getting the good shit.
How many coffees did it say before the visuals kick in?
Friends, don't let friends drink and drive!
