The whole expirience...
But most specifically, I love how it slows down time. I can spend 5 hours just listening to music or drawing, and then look at the clock and only an hours gone by...
I smoke for the peak. When you feel completely sober, and then you get some weed... pack the bowl... turn on the tunes... and light up. And then comes that moment... when your sober face melts into a happy grin... when the guitar riffs suddenly echo and massage your ears... and that huge sigh of releif with the inward feeling of incredible love that this feeling exists without any repercussions. Thats why I smoke.
