So, you're wondering if marijuana smoking (which was unlegalized for a reason).... is bad for you? Are freaking NUTS?
Of course it's bad for you, of course it'll have affects on your body and mind. Why should you quit just to get to your goal, why not just do it for yourself? It's a weakness to be dependent on something...
Here's a quote:
"Q: What are the long-term effects of marijuana use?
A: Findings so far show that regular use of marijuana or THC may play a role in some kinds of cancer and in problems with the respiratory, immune, and reproductive systems.
* Cancer - It's hard to know for sure whether regular marijuana use causes cancer. But is known that marijuana smoke contains some of the same, and sometimes even more, of the cancer-causing chemicals as tobacco smoke. Studies show that someone who smokes five joints per week may be taking in as many cancer-causing chemicals as someone who smokes a full pack of cigarettes every day.
* Lungs and airways - People who smoke marijuana often tend to develop the same kinds of breathing problems that cigarette smokers have. They suffer frequent coughing, phlegm production, and wheezing, and they tend to have more chest colds than non-users.
* Immune system - Animal studies have found that THC can damage the cells and tissues that help protect people from disease.
* Reproductive system - Heavy use of marijuana can affect both male and female hormones. Young men could have delayed puberty because of THC effects. Young women may find the drug disturbs their monthly cycle (ovulation and menstrual periods)."
