I am after a bit of advice which may be of use to all. I would like help in trying to spot the symptoms of drug abuse (i.e. heroin, cocaine,ecstacy and other drugs). I have scoured the internet, which has lots of information but not what im really looking for. What changes of behavior do you expect to see? What physical changes/symptoms should you look for? I have put this thread in here on advice from the MODs, apologies if it has been done before but I did try the search function.
