Brandon101 Marijuana smoke can inflame and irritate your lungs. If you use it regularly, you could have the same breathing problems as someone who smokes cigarettes. That could mean ongoing cough with colored mucus. Your lungs may more easily pick up infections. That’s partly because THC seems to weaken some users’ immune systems.
Marijuana can make it harder for you to focus, learn, and remember things. This seems to be a short-term effect that lasts for 24 hours or longer after you stop smoking.
But using pot heavily, especially in your teen years, may leave more permanent effects. Imaging tests with some -- but not all -- adolescents found that marijuana may physically change their brains. Specifically, they had fewer connections in parts of the brain linked to alertness, learning, and memory, and tests show lower IQ scores in some people
Not everyone’s experience with marijuana is pleasant. It often can leave you anxious, afraid, panicked, or paranoid. Using marijuana may raise your chances for clinical depression or worsen the symptoms of any mental disorders you already have. Scientists aren’t yet sure exactly why. In high doses, it can make you paranoid or lose touch with reality so you hear or see things that aren’t there.
