1) are there any long-term effects associated with taking adhd medications?
2) does day care, preschool, etc. have an effect on children developing allergies/asthma?
3) is breast cancer inherited from other family members?
4) what is the best way a ptsd patient can get over most of their ptsd symptoms?
i would like some really detailed answers, because honestly, i am struggling with understanding some of these and their reasons.

 1)high blood pressure and heart problems, abuse etc

2) Allergies and asthma are mostly have the genetic, familial and immunological background. The day care, preschool will be an stimulating factor in the children already suffering from the disease like asthma.   If conditions are unhygienic at day care and school than it may trigger the attack. so yeah they might.

3) yes example if someones mom had it , it would effect the child , because it’ll be passed on to the child, but the child won’t know till its effects become known 

I’m not sure about  4
