I wasn't expecting much from kanna, considering the negative prior experiences I have had with legal herbs. I bought 3 grams from an online supplier. When the package arrived, they kanna was a greenish powder. I sniffed about 50 mg, and put another 50 into a piece of gum I was chewing. It didn't taste as horrid as others have described.
About 10 minutes later I had a lovely feeling in my stomach. I felt really good. I felt stimulated yet calm at the same time. I definately couldn't compare it to any other drug I have done (which is quite of few). I found to be the littlest things amusing and interesting. I felt fantastic.
About 20 minutes later, I smoked a cigarette which intensified the experience. I felt like I was mildly high on marijuana, yet highly stimulated on caffeine.
About 5 minutes after that, I smoked about a half gram of marijuana. Now, I felt very loose and relaxed. I felt pretty happy, more so than usual.
This happy high all faded away for about 3.5 hours before I was back to baseline. The comedown was very calm and comfortable.
From this experience, I have learned that kanna is a powerfull mood enhancer, and can really lighten a person up. It would be a nice way to unwind after a long hard way. I also learned not to under estimate the power of a substance, legal, or not.
