It is right to focus on supply, which is the focus of the Bill. It is important to give the clear message that the Bill will not ban use, but supply: it will not ban the continued personal use of poppers, but it will ban their supply.
The issues are complicated. There are controls on alkyl nitrites in that the sale of poppers to under-18s is caught by the Intoxicating Substances (Supply) Act 1985. There is a wider debate about whether that is a proportionate response for under-18s. However, there are already controls on supplying under-18s. We need to be aware that this is a complicated area of law, beyond the issues relating to psychoactive substances.
