Why are there so many junkies in Scotland?

Because they need something to make them happy in their sad lives.

There are many many drug addicts all over the world not specifically in Scotland.  However there are a lot here.  Troubled lives is the reason they seek drugs.

It is isolated.

Scotland is the drug capital of Europe,over a thousand deaths related to drugs this year alone,and only now are the government have actually done something about it by opening g a safe environment and are giving out diamorphine to injecting addicts,Sweden and Portugal have been doing this for years and the crime rate dropped 95% overnight so it's got to be a good thing,answer to your question is poverty,and people use illicit drugs to escape from this 

If you were Scottish you would want to get off your head, too.

History of unemployment and poverty in part.

Do you live in both places? If not how do you know ?

They all come up from Engurland innit.
