MP And The Army Take Psychedelic Drugs Shocker. Very British Drug Tests In The 1950's

I have no idea what 'Mescaline' is, and I can't be bothered to copy / paste it into Wikipedia to look it up. It's a bit like LSD from the following video - featured Christopher Mayhew MP in a BBC (Daily Mail would LOVE this) documentary that was never ever shown. Humphry Osmond, the 'dealer' coined the phrase 'Psychedelic', but it would take someone in California with a less British plummy accent to add the 'Man' bit in the 1960's.

Here's this SHOCKING FOOTAGE Daily Mail readers.

You think an MP taking drugs on TV presumingly to make a name for himself / get on the 50's version of I'm A Celebrity Get Me Out Of Here is shocking? How about the Army? Soldiers! On an exercise! With Guns! TAKING ACID?! "1 hour and 10 minutes after taking the drug, with one man in a tree, feeding the birds.."
