I'm writing a short story, kinda longer than the average. Anyway, it involves these kids who are not too bright and they're experimenting with hallucinogens. I just want it to be completely plausible, so that any reader who really knows his stuff about this sort of thing isn't distracted. So, they run across a website that sells a 5x extract of acacia catechu bark and a 10x extract of Syrian rue. They shell out the money. Why did I pick these products? Well, I want it realistic, so I had to pick something actually available. Also, I thought they'd get an extract so they didn't have to mess around with grinding and extracting anything themselves. I'm going to have them just put the stuff in a tea or smoke it...simplest preparation possible...I'm going to write a pretty cool trip for them with some McKenna-esque visuals. How much should I say they used? I've searched around the internet, and the only reliable stuff on dosing I can find involves using the isolated alkaloids. Thanks in advance for any help or advice you can offer with this.
