If marijuana is smoked too much it can irritate the lungs and lead to breathing problems.

It does have some health issues, for instance if a young adult, teenager, or children smoke it a lot and can affect the growth of their brain because our brain as youngsters are still growing.

There are 2 main types of weed: Sativa and Indica. Sativa wakes you up and sends energy to the brain which then spreads out to the body. So instead of drinking coffee to wake up you can smoke 1 or 2 blunts of sativa and you'll be awake. Indica is known to send chemicals to the body to relax. So it could be beneficial to the who has insomnia. Again they can smoke two blunts and they'll be able to sleep peacefully.

Studies say it relaxes the body by slowing your brain, making things all slow. This will relax you when your stressful and you can't calm down or go to sleep.
