For comparison. A few years ago they tried to reschedule Amyl Nitrate (aka Poppers) a drug available as "Leather cleaner" in most sex shops. It was going to put on the same schedule as Heroin making it illegal to possess.

Then after complaint they completely changed to make it an over the counter drug. Although as far as I know it's still not available at any chemist I know of. But you can still buy it as Leather cleaner from few sex shops. (Less than it used to)
