Oh . I am not sure what kind of data Nvidia actually collects . <| sep |> Meth doesn ' t cause your teeth to fall out . It also doesn ' t make you see shadow people or feel bugs crawling under your skin . Meth does make you lose your appetite , dehydrates you , and keeps you from sleeping . Any kind of smoke passing through your mouth is bad for you teeth , and dehydration is bad for them as well . If you smoke meth once every few months , you won ' t experience any of the aforementioned negative effects . That ' s not to say meth is healthy . But it doesn ' t cause any of those symptoms on its own . Those problems arise in meth users because some of them go on binges for days on end , which means they aren ' t getting any sleep shadow people and bugs , they ' re not eating or drinking dehydration and an emaciated appearance , and while they ' re tweaking for days it ' s unlikely they cared anything for dental hygiene , as they were probably too busy waxing their floors and masturbating for hours . It ' s totally possible that the mother you described was indeed a meth addict who ' d been binging , I just wanted to point out that smoking meth will not cause your teeth to fall out as long as you take proper care of your pearly whites .
