In high school I had a brilliant roommate who was about 10 years older than me, when he was younger he had participated in government LSD experiments as a subject.
Your former roommate may not have told you, but if he was still a minor, parental consent was needed. Why would any parent “offer their child up” to a government agency for experiments?
What do they gain from it, since tbey probably couldn’t even brag about it to the grandparents during Thanksgiving Dinner?
I will answer my own question with this: maybe one of his parents was experimented upon some decades earlier.
The family and the DNA had already been vetted.
