Is it safe to ride a rollercoaster or any ride while high on pot?

Because when I went on the steeler I think it was called at Darien Lake in upstate NY, it said that if you are on drugs then u shouldn't ride the ride. I've always wanted to ride rides while high but I haven't yet and I was wondering if it is safe to? Have any of you rode any rides while high or drunk or while on other things? Thanks
