I have not looked into these drugs much, but I know people who have used them. With some you see a real difference. I think anything like that should be used with medical advice as you are changing how your body works and still need to stay healthy. I think some people here can get it prescribed through the NHS, but others will have to pay. I've heard it's having an impact on the clothing market as those who are slimming may buy more.

When it comes to weight there can be many causes for issues, but with smoking you have one industry feeding the addiction and another helping get people off it. Both will be making a lot of money.
