Actually this story was told to me directly from the friend involved. Of course since there were two involved the second person could still be alive. Just ask him (name unknown). For anyone who wishes to know I will disclose the name of the friend who helped send a joint to the moon.
I had a friend who worked on the Apollo mission doing power supply system setup for Apollo 16 (?).
She and her partner got the equipment together for encapsulation and decided to take a break and smoke a joint.
When they got back they had enough for one more joint.
They rolled it up...
