Where did you get the buttons from? The wild? How old were they? If they were under about 10 years old they wouldn't have any mescaline in them anyway.
I'd disagree very, very strongly with that. Authorities knowing that you take illegal drugs is a terrible idea.
Doctors aren't the authorities though. They have an obligation to keep whatever you share confidential as well or else they could lose their license.
I'm not going to say. Isn't talking about sources against the rules anyway? Besides, you guys seem to default to criticism/skepticism lately anyway.
