Stability of LSD in transparent containers under light was dependent on the distance between the light source and the samples, the wavelength of light, exposure time, and the intensity of light. After prolonged exposure to heat in alkaline pH conditions, 10 to 15% of the parent LSD epimerized to iso-LSD. Under acidic conditions, less than 5% of the LSD was converted to iso-LSD.

The double bond between the 8-position and the aromatic ring, being conjugated with the indole ring, is susceptible to nucleophilic attacks by water or alcohol, especially in the presence of UV or other kinds of light.

Both the parent drug and its major metabolite are unstable in biofluids when exposed to light, heat or alkaline conditions and therefore specimens are protected from light, stored at the lowest possible temperature and analyzed quickly to minimize losses. Most serotonergic psychedelics are not significantly dopaminergic, and LSD is therefore atypical in this regard. The agonism of the D2 receptor by LSD may contribute to its psychoactive effects in humans. Tolerance to LSD builds up with consistent use and cross-tolerance has been demonstrated between LSD, mescaline,and psilocybin.Researchers believe that tolerance returns to baseline after two weeks of not using psychedelics.
