Poland and Ukraine (pre-war)).
It is impossible at the current time to keep an up-to-date with the fast-changing scene that governs sodium nitrite. For this reason, it is best to check the Peaceful Pill Forums for on-going discussion of current sources. Once located, sodium nitrite can cost can be as little as US$15/ Kgm.
Note: In 2019, the Dutch government introduced regulations for the sale of sodium nitrite to individuals. In other countries, people who have had sodium nitrite delivered to their home, have received ‘welfare checks’ from their local police.
Note: Some readers who have reported problems when ordering sodium nitrite (because the live in a country where there are restrictions and purchase is difficult) have reported using proxy snail mail addresses (which receive the delivery, repackage it and then send it on). Given there is no illegality surrounding the purchase of sodium nitrite, this has proven a useful work- around strategy.
