In high school, janet rarely smoked or drank alcohol. in college, janet met some friends who spent most of their downtime consuming large amounts of alcohol and other drugs. soon, she did the same and did not know anyone who did not spend their time that way. which theory best explains janet's behavior, given this limited amount of information?

Considering the small amount of information we can only point out to the differential association theory to explain Janet behavior.

Explanation:

The reason we can only do this is that we are analyzing an incomplete scenario. First of all, we don't know the reasons behind her behavior, it could be one or one million. So we can't pursue a theory of meanings behind behaviors. Also, we don't know why she learned the behavior or when. We only know she didn't smoke and drink before them. However, we know that after knowing them she didn't know someone who didn't do these two substance abuse activities. So, we only have the theory of Differential association to explain that Janet did it because she interacted with people who did it. The differential association explains that we don't need reasons to justify someone's actions in a matter of deviance behavior we just need frequency of interaction to be followed.
