Lip joints are ok for smoking on the move but if you are in a house or apartment or dorm that might not take kindly to pot then vaporisers are the right choice. Alot of people dont smoke joints anymore because they dont have the money for a nice joint and would rather smoke a couple bowls instead. Also vaps are so much better for your lungs than joints. With paper and weed after time that is alot of tar build up in your lungs rather than no tar build up with a vap so stop acting like an allknowing twat. You can tell somebody something while being nice you know.
