Smoking Marijuana Everyday?

Hello, I am 16 years of age and I smoke marijuana every single schoolnight, and on weekends. I started smoking about 3 years ago, and have been smoking almost every day for a year and a half. What could be possible negative effects, is what I am wondering. It does not effect my work ethic, Ive gotten one C on a report card in two years. I love skateboarding, and stay active doing this every day that is possible. And I absolutely love to smoke weed, by myself, every night. Is it really possible that I could receive heavy brain damage if I continued this? I'm just generally a more relaxed person, and I feel perfectly healthy every day as well. I would like some info about if this is really harming me or not.

In fact, in the first hour of smoking marijuana, a user’s risk of a heart attack could increase fivefold. School performance is reduced through impaired memory and lessened ability to solve problems also stroke in young people have been reported in studies-
