Did you know that the use of marijuana among teens has declined drastically since the end of the 1990's? If you thought all over the world to smoke marijuana, you were wrong. Statistics show that around 7 per cent, or approximately 1 out of every 14 teenagers, says having used marijuana in the previous month (SAMHSA, 2014). However, there are many teenagers who don't believe that marijuana is a harmful drug. Some believe that marijuana is not harmful because it is "natural". But in reality not all natural plants are good for one; considered tobacco as an example.
