What are the main health risks when smoking marijuana?

I'm an expert on that. The only disadvantage I find is that your lungs tighten up over time worse that cigarettes would. And you cough up flem. It makes you look stupid in front of other people that don't smoke it.AnswerIt causes short-term memory problems (although this typically clears up once the person has quit smoking weed), and it causes lung cancer and other smoking-related diseases, just like cigarettes. Marijuana actually burns about 3x hotter than cigarettes witch would burn the hairs in your lungs faster witch will create cancerous cells to spread faster. It also coats the neurons in your brain in THC and wont allow the neurons to connect, basically saying that its going to make you dumb. And the only reason why you feel high when you smoke it is because the THC is choking your brain of oxygen as the result of the floaty goofy feeling.
