Unless smoked daily, in very high volume, over a very long period of time, cannabis is not physically addictive.
However when smoked regularly, even in small amounts, cannabis can be psychologically addictive due to the principles of conditioning, state-specific memory and amotivational syndrome.
cannabis is only psychologically addictive, kinda like because it feels good, so the hard part in quitting is u missing that feeling and not ur body. In that case it probably means ur not focusing in ur life enough to be thinking about трава if ur trying to quit, или ur not doing something that makes u feel good without needing to hit the bong или smoke da spliff xP
