I honestly don't know anyone at my uni who does drugs, or at least they don't make it obvious.
But certainly none of my friends do anyway.
I guess it varies a lot on what course you do though as I know on my brothers Art degree loads of people took drugs for example.
i am not into drugs at all..but 70% of the students in my A levels were all drug users!..
nope not a fan of these stuffs, but have friends who do all sorts, so yeah..personally, i hate smokers, but wouldnt mind a special brownie..hehe
Not all students, infact most of the people I know don't do drugs but they are easily available and I know people on both ends of the scale i.e. some do loads of class A's, some have the odd spliff and the majority just stick to drinking.
