There is much debate whether smoking cannabis is less harmful to the lungs than smoking tobacco. It is clear that smoking cannabis still carries the same health risks that come from combusting any substance and inhaling the smoke into your lungs. For this reason, vaping is another popular form of cannabis inhalation. Vaping devices deliver concentrated forms of cannabis with fewer inhales than smoking, and may be a healthier form of consumption. http://blog.ratebe.com.au/...y-Aims-To-Learn.html Cannabis affects its users differently, and for some first-time smokers, it will have no effect on them at all. This was true not only for my first-time experience, but many of my friends as well. This experience is not uncommon. If you don’t feel anything after smoking your first time, repeat the process and make observations of your experience. Some first- time users report feeling light-headed, while others  experience a complete sense of euphoria.
