this. vaping a sativa weed will still give you a head high, it just doesn't hit you as quick because your not getting that buzz from all the smoke. if you REALLY want a strong body high, get a heavy indica (like he said, most kushes, or something as purple as possible). why are you against edibles also? just take 8 ritz crackers, spread nutella on em all, grind up your herb super fine and cover each cracker, then put them together to make 4 bomb firecrackers. now just cover and let sit for a few days, no heating necessary. eat one and you will be couchlocked, guaranteed
