Unfortunitly, I have spent many-a-time in treatment plants and have inhaled my fair share of 'methane'. First hand experience suggests that the only high you get is 2 hours later while at a local pub thanking Gawd your done for the day while whistling down your third beer all the while completely understanding why no one will sit within 3 bar stools of you...

For what its worth, you can catch a buzz by holding your breath till you pass-out. Its cheaper and as stupid - just like sniffing shyt juice!
