Reply to comment by SwansonHOPS in Intensity of psychedelic experiences after taking psilocybin does not depend on body mass index, study suggests by nikan69

For the same reason I gave here:

More mass = higher necessary dosage. A greater volume of blood/body fluids means a more diluted product in the bloodstream. Beyond a certain dosage the effect might be similar because you've saturated the receptors. Not sure that applies here or not, probably not since higher dosages are linked to more intense experiences.

The only two drugs I know of that are mass-dependent are DXM and alcohol. Where are you getting that, in general, more mass = higher necessary dosage?
