LSD vial evaporation?

[Vlad622]

I got my hands on a vial with 10mg LSD about 6 months ago. About 1mg was used up in the first month, then it sat in a cool, dark desk drawer untouched for 5 months. Now it appears as if there is significantly less liquid in the vial. Am I imagining it or is it likely some of the solvent evaporated? Would I be right to assume this means the remaining liquid is more concentrated with LSD?

I think it's possible so be careful the next time you take any. I would mark where the level is now as a reference just in case more happens to evaporate.
