BS! No one has to breath it, it's easily absorbed through the skin.
Back in the early days of acid (when it was legal), there was a chemist named Owsley who made it all the time. His pad was very popular place to crash, as the hippies would get off big time just on what they absorbed from sleeping on his floor.
...What's there to live for?
Who needs the peace corps?
Think I'll just DROP OUT
I'll go to Frisco
Buy a wig & sleep
On Owsley's floor ...
