Based on the information given, it can be noted that the problem with the research is the problem of validity.

Problems with validity.</h3>
It should be noted that in a research, a problem with validity takes place when there's a lack of reliability of the independent variable.
Also, it is a result of lack of representativeness of the independent variable and a lack of impact of the independent variable.
In this case, the researcher sets out to measure drug use on US college campuses by asking a representative sample of undergraduates whether they are currently receiving federal grants or loans. It should be noted that the question asked doesn't relate to the research.
In conclusion, there's a problem with validity.
