This pen packs a punch! It leaves you with a decent, pleasant high. I do have to say, it definitely creeps up on you though. I will go from totally normal to dummy stoned in a matter of a few minutes and not even realize it lol.
This is my second time buying these because I like the rapid onset and they have a nice relaxing buzz. Only negative is that I often get a headache if I take a whole one so I take half and wait an hour to take the other half. I find this really extends the feeling.
