I bought my SN from the auction site (UK) about a month ago. There were a number of sellers listed. Now when I search for it nothing comes up, the one I bought from is not listed. Is SN sales being restricted now in the UK at least?
I have given replies to this question on several occasions, but I suppose it bears repetition as there is so much to plough through on the forum, and there is an ever flowing stream of new members.
My points refer to the situation in UK.
UK legislation places poisons into two classes, viz. Regulated and Reportable.
Regulated means that possession, acquisition and supply requires a Home Office licence.
Reportable substances do not require a licence, but responsibility is placed upon suppliers to report any suspicious transactions or attempted transactions to police. Some guidance is given on what "suspicious" means, and inevitably many legitimate suppliers err on the side of caution.
Sodium Nitrite is currently placed in the Reportable category.
A little over a year ago the UK Government appointed a new Junior Minister in the Department of Health, with special responsibility to prevent suicide. There have already been two incumbents in this post (last time I looked). It seems pretty obvious to me that the increase in interest in the suicidal properties of SN will have attracted the attention of this department, and the attention of legit SN suppliers will have been drawn to their reporting responsibilities.
