Here is a contact to the MSDS on ritalin.
The LD50 numbers are going on for mid page (LD-50 = dose at which partially of subjects die).
The LD50 depends on the cargo of the subject.
It depends entirely on the mg's of the tablets.
This depends on:
1. Person's substance and age and sex.
2. Any pre-existing form problems human being may enjoy.
3. Other medication soul may be taking.
4. The mg of the tablets (5, 10, 20?).
5. The sensitivity of the character to Ritalin.
6. The method of ingestion (oral, nasal, injected?).
Sorry we can't be specific! If you or someone you know is abuse Ritalin, you or that someone else should stop. (Like you don't already know that.)
I'm 6' 1" and 186 lbs. My prescription say to pilfer 20 milligrams per sunshine, 3 times per sunshine. I'm also on Concertta (which I've hear is a long durable altered copy of Ritalin) 36 milligrams once per hours of daylight. In short, it's economically over 60 or 70 milligrams.
