>>10808572>I have amphetamine in the form of ritalin 10mgRitalin is methylphedinate which is not the same thing as amphetamine. They have some structural similarity and physiological effects but still two different molecules.
I'd suggest you calculate the molarity when a 70 kg man ingests 30 mg amphetamine sulphate. Lets say the man is 70% water so roughly about a volume of 50 liters. Molecular weight of amphetamine sulphate is 368.492 g/mol so it would result in a molarity of c= m/MV = 0.0000016 M = 1.6 µM.
Ritalin has a molecular weight of 233.31 g/mol so if one tablet is worth 10 mg then you'd need a volume of V = m/Mc = 26.8 liters.
So this is overall a very crude approximation but start with one pill in 26.8 liters of water and work your way up from there.
