After the meth problem in america became rampant (and is still a huge problem in many places) it was hard to get pseudoephedrine so instead there were many drugs that just got me high (in a non fun way) but didn't actually clear my sinuses. Obviously this is anecdote but I think it is not fair to call out other countries without proof.
Well, if blog posts are the currency of credibility one can get away with many things. The allegation may well be correct, but for the purpose of the discussion and level playing field, lets stick to more traditional sources of information and claims.
BTW I see that you got downvoted. Lest you think so, it wasn't me.
