A friend asked me what I always do on the SDMB and I told him that the people here could answer any question, regardless of content. He doesn’t believe me, so he posed this question to me for an answer.
Let’s say that he smokes an ounce of weed a week using mainly a single chamber water bong with ice, and occassionally glass pipes, joints, blunts, etc.
Let’s also say that he’s been smoking for 5 years, and has maintained his current dosage for about 2 years. Let’s also say that he has no plans to quit in the near future.
What are the chances of lung cancer forming after X many years?
I suppose the basic question is, how carcinogenic is marijuana?
