^^This makes a lot of sense actually. Because n oxides are not observable in GC. SWIMs friend of a friend has tried very hard to find something besides buf in buf extracts that cause pain. in GC there is nothing but buf but if buf n oxide was there it would convert to buf during the analysis. this also might explain why roasting the seeds help. maybe it causes the n oxide to break apart bak in to buf? or just break apart into something that doesn't cause the pain and has no effect allow the buf to work on its own.

any TLC methods for n oxide detection? SWIM will check it out.
