I practically guarentee there was tobacco in that joint. This is my reasoning why you whiteyd. Try smoking ONLY cannabis, through a bong or pipe, trust me on this. It makes the world of difference. I know all of your friends probably only smoke joints mixed with baccy, but fuck it, try a bong man! Not an acrylic one either, not one with a carb hole, get a good glass bong, with a slide and you will have good times. Don't let it discourage you, get back on the metaphorical horse and toke away. You don't need to smoke a joints worth to yourself. Half that is fine.
