Ahh, the O Pen. I love vaporizing. Absolutely love it. Being an avid runner, I try to take care of my lungs somewhat. The problem is, most vaporizers are too bulky, leaving me packing a joint for when I go on a hike or a long drive.
But not with the O Pen. The O Pen is an ingenious cartridge that connects to any standard electronic cigarette battery. One 5-10 second pull and the medication is being delivered. And it lasts a good 2-3 hours.
They come in 1/2 gram and full gram cartridges, and retail for anywhere from $40-$70 a gram. I paid 50, and it was worth it. Sativas, Hybrids, And Indicas are all available. I went with Grandaddy Purple.
