I do have a still, but alcohol is so cheap I just let it go. Many "lab" fires are from reclamation efforts, usually mis use of ether. Even with ether back in the day, and as hard as it was to get lab grade ether (metal can like brake fluid came in) I still let it go to the sky. Plus, my efforts are small, for my own use.In the day with ether, i still did an alcohol extraction first. Much less than trying to extract the weed with ether! That, and you would need a whole new setup....the little Isomerizer was never ever ever intended to use anything but alcohol, NOT ether! That would be a disaster. Ether fumes are more explosive the gasoline, which is insanely bad.
