Why sponsor here
Because your audience is inside and the big platforms have shut the door on you in writing. That is not an impression: it is in their published policies.
Google Ads bans advertising for “instructional content about producing, purchasing, or using recreational drugs”. Its only exception, topical CBD, can be targeted to three US territories: in the European Union there is no route at all.
Meta bans promoting illicit or recreational drugs “or other unsafe substances… as determined by Meta at its sole discretion”, and the paraphernalia too: “bongs, rolling papers and vaporizers”.
- A hyper-segmented audience. Anyone who opens Noosphere is already inside the subject: researchers, clinical staff, psychologists in training, specialist journalists, postgraduate students and harm reduction services.
- Context that lends credibility. Your brand does not sit next to clickbait: it sits next to cited evidence and a declared level of evidence.
- No noise. No programmatic advertising, no tracking, no pop-ups. One logo, right there, is seen.
- Thirty years behind it. Noosphere is a project of Psiconáutica.org, which has published on psychoactive substances without interruption since 1996.
About audience figures, up front: Noosphere launched in 2026 and has not been
promoted yet. Impressions are not what is being sold here, and you will not find
inflated visit counts on this page. What is published are the corpus figures, which
are large and can be checked one by one. If you need usage numbers to decide, you
get them exactly as they are — just ask. Whoever comes in now comes in cheap, with
the rate frozen for two years.
Where your brand would go
Never inside an answer and never inside the graph. Always around it, labelled and static. This is exactly what it looks like:

What no sponsor can buy
It is in the contract that gets signed and in the editorial policy. This is not ethical decoration: it is the reason your logo, sitting there, is worth something.
- Influence over the corpus. Not which documents go in, not which come out, not how they are weighted.
- The sponsored answer. There is no such thing. No query returns promotional content and no source is ever cited for money.
- Sponsored nodes in the graph. That would falsify the object of study.
- A right of veto. If a document in the corpus criticises your sector, it stays and it can be cited.
- Seeing anything before the public does, except your own material.
Nor do we accept anyone selling controlled substances, retreats offering them on Spanish territory, unproven claims of cure, anyone asking to install tracking pixels, or anything aimed at minors.
How to book
- Write to us saying what you sell and to whom. We confirm free slots and dates — or tell you that you do not fit, which also happens.
- A two-page contract. You can read all of it before deciding.
- Artwork five working days in advance. If you have no dark-background creative, we prepare it at no cost.
- A monthly report of impressions and clicks, measured on our own server and without cookies.
Artwork specifications
- Optimised JPG, PNG or WebP under 120 KB. SVG for logotypes.
- Prepared for a dark background (#06070F): logo in white or a light version.
- No third-party JavaScript, no pixels, no tracking cookies. If you need to measure, we give you UTM links and our own counts.
- No animation, sound or auto-playing video: this is a working tool.
- Links carry rel="sponsored" and the block is labelled as sponsored.
- One creative change per month at no cost. English translation included.
Invoiced from the Canary Islands: IGIC at 7% applies instead of
mainland Spanish VAT at 21%. The same sponsorship costs you 14% less than booking it
on the mainland.
