Sounds like you are talking about a blunt. That's a hollowed out cigarwrap that is filled with cannabis. There are many different types of cannabis and there are many different types of highs as well. All types of highs will mellow you out, but the degree varries. The high can be mostly in your head or mostly in your body, but most are a mix. There are two main types of cannabis plants, indica and sativa, but most cannabis is a hybrid of the two types. bud with seeds and lack of scent is usually what people call schwagg and it is very low grade, you can get mid grade, with some seeds, but usually seedless cannabis is the strongest. You can pick up a gram oh good kindbud for no more than 20 bucks, but you will not want to smoke even close to the whole thing. Just break off a little piece and smoke that first and see how you feel. You can check out sights like www.overgrow.com or www.thecannabible.com to get a little more information than a few people can type out for you. It's great that you want to research something for the real facts before trying it. Good luck and don't overdo it your first few times.
