If you've never tried it before, something great to do when you're home alone and you want to just get stoned out of your mind by yourself is to listen to music, but not just any music...try listening to some stuff that you wouldn't normally listen too, try finding new bands and new songs that you enjoy or completely new genres. Explore the power of music, because there's nothing that has a stronger bond with marijuana then music, they go hand in hand.
For example, techno usually aint my thing...but one day I was doing this and came across an english band..and all I can say is damn...get stoned and watch this.
