to me it seems the problem with eating would be dosage. since the amount of mescaline is different in certain cacti how much would be good for a 8-10 trip hr and not be buggin for a few days. i only kno one person whose done it and she might have made tea. all i know is that she drank about a nice sized cupful of it and was tripping pretty hard for bout 3 days. idk if it would be tea or not she told me they had the san pedro in a pot boilin for about 7 hours, cooled it down and just drank it. she drank a good amount but is that a possible way. or was she bullshittin me.
