I recognise the concern behind the question, but, with respect, I don't think it's simply a question of the Government having discussions to try and reduce this matter, because there isn't a simple answer. The UK Government in 2015-16 passed the Psychoactive Substances Act 2016, which introduced a blanket ban on a range of psychoactive substances, and that tries to take account of the fact that there are a range of new substances coming into the market and into this country on a fairly regular basis. Many of those are cannabinoids, as indeed spice is.

What we are trying to do is to understand what we can do to reduce harm. Now, simply trying to ban all these substances isn't it on its own. It is also about trying to understand how we educate people about the risks, it's also about how we understand the risks that are being run. That is why the Welsh Emerging Drugs and Identification of Novel Substances service in Wales, which helps to test substances from across the UK, is well used and well respected. It is really important for individuals, helping them to understand the risks they are taking, but also from a treatment point of view, to understand what is potentially in people's systems. There is a constant and never ending discussion about what we need to do to try and manage the demand that comes in with the range of social challenges that we face, but also the range of new substances that are appearing in our communities, and then the response between health, local authorities, the third sector and the police to try and manage this in the most sensible and effective way possible. But this is not easy, and I will not pretend that it is.
