=== Overdose scaling ===

For reagents that have an unreacted purity lower than 100% and an overdose effect, the dosage at which you overdose is not set in stone. For these reagents, the overdose dosage is lowered by how much purer the reagent you are taking is compared to its unreacted purity. The inverse, however, is not true. The overdose dosage can not be raised by using a reagent that is less pure than its unreacted purity. For clarity, a number example:

* Ephedrine has 75% unreacted purity
* You create ephedrine with a purity of 100%, which results in a decrease of 25% in its overdose threshold
* As ephedrine has a 30u overdose dosage normally, 30u is multiplied by 0.75, resulting in 22.5u being the true overdose threshold
* You apply a patch of 23u pure ephedrine to yourself, thinking you are safe. You overdose.
