A recent study proved that children of drug addicts are more likely to become drug addicts, than the other children. The likelihood of this happening, is determined by which parent is the drug addict. This holds true, even if the children are separated from their parents at birth.
Assuming this information is true, which of the following conclusions is most appropriate?
1
Drug addiction is possibly linked to genetics.
2
If the mother is a drug addict, the tendency of the child becoming one, is greater.
3
Treating drug addiction is difficult, as it is an inherited disease.
4
None of the above.
