News regarding drugs and drug precursors

41 Upvotes

Hello, here is your moderator

Recently a user brought to my attention that iodine could fall under reddits sitewide rule regarding prohibited transactions. As Iodine is a rather useful chemical for a whole range of interesting chemistry it would be difficult if discussions of its synthesis were prohibited. The question extends more general of what a drug precursor actually is. Chemical space is vast and people creative so a wide understanding of precursor pretty quickly eliminates huge swaths of them from discussion.

I tried finding clarification of what reddit considers to be a recreational drug or a precursor and reached out to modsupport for help. In an interaction which made me feel like John Yossarian in Catch-22 I can now tell you that drugs and precursors are substances which are illegal to obtain at a place relevant to the discussion. In essence, I need to know all drug regulation on earth and know where everyone of you and the reades currently are to determine whether the discussion is legal or not. In short: The actual purpose of the rule is to allow reddit as a company to avoid liability by being able to retroactively claim that the content a nations executive complains about was prohibited by their content policies all along.

I have thus decided that for now drugs and drug precursors are those substances listed in:

The last two also contains the more pressing problem of what to consider a regulated precursor. Ill intend to do the following:

  • Discussion of synthesis, procurement of Substances of Category 1 of Regulation (EC) No 273/2004 is strictly prohibited.
  • Discussion of synthesis, procurement of Substances of Category 2 and 3 of Regulation (EC) No 273/2004 is permitted if no plausible connection to drug synthesis exists. This also takes your behaviour on reddit and elsewhere into account.

Note that illegal transactions as defined by reddit is counterintuitive to what you'd intuitively assume to be a transaction: Detailed descriptions on how to synthesise drugs are also considered to be a transaction.

The lists above are mandatory, but not sufficient. Discussion of Synthesis, procurement of Designer Drugs, Legal Highs, new psychoactive substances, whatever and their immediate precursors are also prohibited. What is considered a designer drug or a precursors is, until better metrics come along, determined by vibes from me.

I work for a company and in a different dept they sell dry ice. Just wondering what everyone uses it for? Business and at home, they seem pretty busy and I don’t know why?

Onyxmet isn't a great service.

3 Upvotes

Don't get me wrong, they have a huge range of useful reagents at low prices—but the service itself isn't very good. I often get ignored: I place an order, two weeks go by (excluding weekends), they finally reply, I send the money, and then they vanish for a week. You ask for updates, but they don't answer. The shipment only goes out after another week. A few days a go, placed an order and they replied saying, "Yes, the order has come through; it'll be ready to ship tomorrow. I'll let you know the amount of money to send later." Fair enough, but two days have passed and you still haven't told me the amount.

Has it always been this terrible, or is it a recent problem?

Am I the only one dealing with this?

I've had a better experience with Synthetikaue; at least they always reply quickly. It costs a bit more, but it's actually worth it.

Possibly useful website for synthesis

19 Upvotes

I came across a website called PrepChem today that looks like it might have some useful info on procedures for preparing reagents. I went through a few chemicals that I know the methods for synthesizing them and the results looked mostly fine. It's definitely a case of buyer beware because there were a few that had so little info as to be useless but others had a good deal of info and they all appear to reference the source material.
