The ISU drug scene is basically whatever you want it to be and whatever you make it. Drugs can definitely be found, but students have to look for them. This makes drugs not a major issue on the ISU campus. There just really are not a lot of problems.
Students can find social scenes that have drugs and those that do not. Both are here at ISU, but the latter seems to be more prevalent. There are not a lot of students showing up to class high or on something. This may just be because they did not make it to class, but overall, the drug scene is more low-key.
