My hon. Friend raises a very plausible scenario, but I am not aware of any specific evidence to suggest that. There is quite a strict regime in approved premises around the behaviour of residents. For example, they are required to abide by a curfew and their behaviour is very carefully scrutinised. If their behaviour is in breach of the rules, there are possible sanctions that could ultimately lead to a recall to prison. However, he highlighted a danger area. At present, most of the concern is about the wellbeing of individuals in the premises and, once they leave the premises and move into the community more widely, the danger of their continuing a drug habit that would likely lead them to engage in illegal behaviour. But ideally, the further testing that the Bill would introduce would reduce the chance of people succumbing to that temptation.
