00:00Everyone thinks vaping is safer than smoking.
00:02But new research says it may lead to lung and mouth cancer.
00:06Millions of people use e-cigarettes every day.
00:09Most of them are teenagers and young adults.
00:11Scientists reviewed global studies on vaping.
00:14Their conclusion was alarming.
00:17Vapes release aerosols filled with chemicals.
00:19Some of these chemicals are known cancer-causing substances.
00:23They can contain metals like nickel, tin, and lead.
00:26And toxic compounds like formaldehyde and acrolin.
00:30These substances can damage cells inside your body.
00:33They can also cause inflammation and DNA damage.
00:36In lab studies, vaping even caused lung tumors in mice.
00:39Doctors say the damage may not appear immediately.
00:42But biologically, the harm may already be happening.
00:46Today, about 7% of Americans use e-cigarettes.
00:49Researchers say long-term human studies will take years.
00:53But the warning signs are already clear.
00:56Vaping may look harmless now.
00:58But it could be creating the conditions for cancer later.
01:01later.
