^^If your bark is not bunk, then you could get upto 500mg-ish, or perhaps a little less.
Naptha is basically lighter fluid as used for filling a zippo; this is probably the easiest (but perhaps not the cheapest) way of getting naptha.Just make sure you ensure that on evaporating it leaves no residue.Swan Extra-refined lighter fluid, as found in England, works well.
I am paranoid of my brain. It thinks all the time, even when I'm asleep. My thoughts assail me. Murderous lechers they are. Thought is the assassin of thought. Like a man stabbing himself with one hand while the other hand tries to stop the blade. Like an explosion that destroys the detonator. I am paranoid of my brain. It makes me unsettled and ill at ease. Makes me chase my tail, freezes my eyes and shuts me down. Watches me. Eats my head. It destroys me.
