Since one use can last for eight hours or more, you'd only need like nine doses for a 3-day trip, if you stayed up 24/7. I don't see how it could be possible to build a tolerance to the point of it being completely ineffective that fast, when many people have taken far more than nine doses over their usage.
it isn't that it is completely ineffective, its that the intensity of the high goes away very quickly
often, drugs of abuse are about chasing that high
like, tolorance isn't the single reason why halucinogens are not considered to be a high risk for abuse, but it plays off a lot of the other factors that cause drug abuse.
You pretty much hit the nail on the head though, another huge reason is that the only people who really take that amount of LSD are those who want that type of trip, rather than typical abuse situations, where people are self medicating.
