Yah that happened to me about six months ago and I still get pissed.
My friend insisted that you could get high off of banana peels.
We argued forever me telling him it was bullshit and that I had actually found proof it was fake and him insisting that it was true and his friends had done it.
The most frustrating part was that we werent even talking about some foreign crazy drug he actually thought that this was how PCP was made.
GODAMN HIM! I got mad all over again just typing this post.
