I've come to the conclusion that gravs are shitty. Sure, they get you super blazed but seriously...
First of all, gravs take away from the days of social smoking. Up here at college gravs are probably the most popular way of smoking. I know I'd much rather pass around a bowl, bong, joint, blunt or anything else because you get to have the good conversation around the bud. Whereas with a grav, people sit around, wait their turn, get an ungodly amount of smoke, and then are too retarded to talk. This is the worst thing about them.
Second, I think they are just too much for the body/mind to handle. If you pay enough attention like I have, you'll notice people's speech, movement, and lots of other stuff gets messed up after a grav to the point where you look stupid as shit in public. In the long haul, they also dumb you down when you're not even high, make you a lot lazier, etc.... I also have a feeling they are horrible for your health and no one has looked into it yet. Gravs are still pretty much an underground thing (ever heard one in a song, seen one in a movie?) so they probably haven't been researched but all that smoke at once plus the possibility of fumes coming off the metal piece at the top can't be good. I'm really curious what people would find if they studied the effects of gravs on the body and mind.
Third, if you're someone trying to boost the rep of weed, gravs look terrible to someone who hasn't/doesn't smoke. Seriously, think of how ILLEGAL a grav looks, like some kind of crack pipe or something to the uninformed person. This brown bottle sitting in smelly water with a burnt metal socket sticking out of the top... a nice colorful piece or a joint looks much more respectable and inviting.
That said, if you're about to walk into a movie or something where no social skills are needed and you want to be high for hours, a grav or 5 is cool with me. Just not as a main way to smoke. Should be more of an accessory.
What do yall think about this, anyone ever thought of these things?
