Mild--good for a beginner to take one, then another if that doesn't work. Takes about a half hour to start to work, then really working at one hour. I take two of these to help with jaw arthritis. Makes me happy for a bit as well.
Two hits of this and I felt nicely relaxed and I was slightly talkative (I'm not a talkative person usually). However, I took way too much of this the first time I tried it. I was stuck to the couch and couldn't move, and I was also very dizzy.
