Dependency and Overdosing

[Locklave]

Pawns have the following dependencies

Wake-up, Alcohol, Smokeleaf and Psychite. All grant x0% chance of overdose.

They use

Wake-up, Beer, Smokeleaf and Yayo.

Overdoses are happening on all pawns randomly from 16-38 years old. I've hear something about using multiple hard drugs cause a multiplier chance of overdosing but anything x0% is still zero. Basically none chance times 4 is still none.

So I'm confused as to what exactly is allowing them to overdose because these drugs can't cause overdoses in pawns with these genes. The only thing they should have to contend with is tolerance.

Well if anyone happens across this I discovered the explanation with some help on the steam forums.
