There are many types of cancers (and many types of brain cancers) and as far as I know there is no particular recreational drug that is known to cause cancer. Rather than worrying about something that probably will never happen, you might be better served to try to examine the role of cortisol production in relation to inflammation and the relationship between inflammation and cancer. Worrying turns out to be a very lethal drug!
i ALREADY GOT THE CANCER, SO i WAS JUST CURIOUS IF i MYSELF WAS TO BLAME IN SOME WAY. bUT IT SEEMS LIKE BRAIN CANCER IS A QUESTION ABOUT BAD LUCK MOSTLY. sHIT HAPPENS
I'm sorry that you have cancer. My husband is dealing with it right now and that's a helluva world to be thrown into. I went to a conference last year called Healing Journeys that was started by a woman that has been dealing with cancer and treatments for over 20 years now. She has an interesting take on "Did I Cause My Cancer?"
I do think that genes play the biggest part in whether or not you will develop cancer. Again, I'm sorry for your cancer (and sorry for assuming you were unnecessarily worrying about it).
