I chewed a couple of rolls of cope a mo for a yr or so---roughnecking, working fire lines, doing hot tie ins on high pressure gas lines,etc. I dunno, it kinda gave me a buzz and calming effect---ya, I'm weird. Got shrapnelled in the face on one wreck, cut all the way thru----chin and cheek. Was VERY lucky the nurse/practitioner in area had done a plastic surgeon block. AS he was washing up, he casually remarked 'Y'know, you chew, it don't heal...."
Had to ask myself---'it don't taste good at start, it's expensive, it's gross, it's addicting--wtf is the matter with you?!
ps---if you get face cuts, keep it greased with raw, virgin olive oil . This was from the old whiskey drinking retired m.d. in that village.
