and disagree. Education: yes. Using erowid as a single source: definitely not.
My nephew found an old tank of freon from an A/C service cart at a diesel repair shop. After reading the info and reports at erowid he believed he was perfectly safe to inhale from the tank. Apparently none of the reports and info on erowid mentions the dangers of inhaling freon from an A/C service machine: which is full of oil and contaminates from all the service discharges performed.
My nephew got more than he bargained for. Fortunately the I'm-sure-I'm-dying spell only lasted a couple days and only required one trip to the ER.
I would have told him, had he simply asked. However, not so sure he would have listened seeing as how brilliant the internet has turned him.
