It's impossible to tell you exactly what it would feel like for a few reasons; a) It'd be impossible to predict the reaction your body will have to THC, unless you're allergic or just don't like it, its generally really good. b) It'd be impossible to predict what strain, named or otherwise, you get the first time you smoke. c) It depends on how you consume it. Bong ~ 35% THC from bud
Joint/Pipe/Blunt ~ 28% THC from bud
Vaporizer ~ 92% - 96% THC from bud
Edibles - depends on how concentrated the cannabutter is. 15% - 95% THC from bud
Hash Oil ~ 85% - 95% THC from bud
It's really hard to explain, and varies from person to person. It generally just makes you feel, well, good. Myself, for example, it makes me feel more relaxed, more confident, and less worried of consequences in general (not to an extreme, stupid things, like falling and getting hurt while skating.). It depends on you, what you like, how it's done, and who you're with.
