agreed....i never purged mine, until a buddy found out that i wasnt purging...he then went on a big rant about how bad the butane is for me and this and that...so long story short, i went a bought one....i still purge every batch, but honestly on a side by side comparison, you cant tell any differences between the smoke...i never once tasted butane in un-purged oil...just sayin
it seems the more people that learn about the process, the more complicated it becomes. then they build this "hype" which is based on nothing but "hype". i find it often DISCOURAGES people if you make things too complicated.
i have never seen anyone who purges it actually take the time to dry it right. seems the whole point of purging is to rush the process.
purging oil = quick drying bud
