I have written about macro-dosing weed in the past. It isn't exactly psychedelic but I would call it psychedelic adjacent lol.

What kind of dose are you recommending for one who wants to do this? I typically say more than double the amount that one considers to be a normal dose is usually sufficient to get a person to that other level of high. From there, you can always pile some smoke on top of your edibles if you wan't to go a little further in a more controlled way. That being said, I have eaten as much as 1/2 ounce of flower sauteed in butter and honey in a single sitting which is way more than a double dose lol.
