In fact, before COVID-19, N was widely available and easily sold online, even in countries like those in Latin America. It's the product often used for euthanasia and assisted suicide in countries where it's legal, and also for veterinary euthanasia. This product was so successful that it prompted investigations by many authorities in various countries around the world aimed at shutting down sales networks. Now, only scammers remain. To make matters worse, the PPH book and its updated online version, PPeH, published by Exit International, which also listed N sellers, are no longer accessible because Exit International has blocked access for people aged 50 and over, thus blocking access for anyone younger. Since around 2021, there are no more reliable N sellers, no way to get PPH or PPeH, and now SN (which is the poor man's solution) is becoming increasingly restricted because more and more authorities know that it is used for CTB!
