I will look into making it an option. I think it already removes any active addiction on birth, but it may make sense to block it in the same way you can block them working when younger.

Could you otherwise restrict the drugs for them or restrict them from going into where they are stored?

I couldn't think of anything apart from:
- setting up a no drug policy, which didn't work, as chemical fascinated pawns ignore such silly restrictions;
- setting up a no-kids zone where medical supplies were stored, which I think worked, but whenever some raider was killed the babies were often at the corpse earlier than anyone, snorting yayo and dying.
. In the end I simply hacked them with a character editor and removed the problematic trait from all babies.

I'd really appreciate if you could look into that, since it looks more like a design problem than a difficulty problem. :)

Try this as well (just edit out the trait)

@ПΛПО Dragoon This is exactly how I removed the problematic train from my kids. I literally wrote that. :)

I just updated the mod, there is now an option to have the 'need'-effect of an addiction subdued until a certain age (default is 5 but you can configure it 'Young can't get addicted until')

It seemed to work ok for me in testing, they are not completely prevented from taking drugs it just takes away the 'forced to take'-need from the addiction until that age. (so it still also depends on your drug settings, if social is ok, they will still randomly take thing like everyone else)

Thank you for the continuous support!

Remember kids, spay and neuter your junkies, only you can prevent child psychite overdose.
