Tar in cigarettes cause lung and oral.

Cancer because of the constant use of them and the niccotine inside as well as the numerous types of poisons inside the ciggerette and the smoke.

yes, it is pretty much the same thing, which is cool. : )

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.

hope this and can i get bainliest my dude : d
