if it's his first time he probably won't feel it much anyways, unless he avidly smokes grits...

for the first time i suggest a bong, cleanest, smoothest hit you will get aside from a vap. just don't give him HUGE chambers full. that's the beauty of a bong, you can measure the amount of smoke you would like to consume. That way you can regulate how much he takes in too

ohh and don't mix bacco and weed, that's just nasty, bacco is dirty dirty stuff. wait wait, unless you smoke shwag, then it might be an improvement over the herb

all in all, if its his first time make everything seem NORMAL to him, chill at home and listen to music, play video games, or go for a drive and blaze the spliff as you roll.

just have fun
