drug dosages depend on what ?

[Ximot]

body weight?
--a factor for some drugs like ketamine or alcohol, for instance, but not others, e.g. not for paracetamol it seems

tolerance?
--depends on the drug a lot.

sex?
--m/f/... (to do with body fat and metabolism and...?!)

individual differences in sensitivity
-- (due to enzymes or whatever?)

food intake prior, obviously...

I especially welcome people's experiences on which drugs' dosages are affected by body weight and which ones aren't. Particularly keen here on RCs, but any info welcomed.

peace

they also depend on race.. several medical/pharmpacy R&D companies have started to take this into account in their research.

Many people think that size has a big influence but iv been told that the bigger the persons build can give more effects that someone who is small. Iv been told that this is the case with GHB. anyone any personal experience

Are not attitudes and expectations important too, especially with psychedelics?
