There'v been quite a few raids in Stratford over the last couple of years: http://www.coventrytelegraph.net/news/local-news/drugs-raids-hit-stratford-bid-9419445

Sadly a never ending fight. As quick as one dealer is taken down another springs up.

I'm really not sure if we ought legalise drugs or not.

One thing's for certain, how we currently deal with things doesn't work.

Once one dealer disappears, another always seems to turn up to fill the gap. However, I occasionally hear statistics on the news that the long-term trent for taking drugs is on the decrease.

Just found some statistics: https://www.gov.uk/government/publications/drug-misuse-findings-from-the-2013-to-2014-csew/drug-misuse-findings-from-the-201314-crime-survey-for-england-and-wales

I think we need to treat those figures and graphs carefully. The underlying data can't be particularly sound and there are many imponderables. There are also no confidence figures or uncertainty figures given, (unless I've missed them) which for a statistics authority is a little naughty.
