What is the boiling point and density of LSD?
Lysergic acid diethylamide doesn't boil. It decomposes. The density is $1.2 \pm 0.1~\mathrm{g~cm^{-3}}$.

Data can be found at  ChemSpider. There's a predicted boiling point of 541°C. However, lysergic acid decomposes at its melting point of about 240°C (CRC Handbook of Chemistry ad Physics, 64th ed.). This suggests that lysergic acid diethylamide does not have a real boiling point - at least at normal pressure.
