Don’t you see. The symptoms and cases are too isolated to make a claim of cause. And honestly I suffer from a congenital colon disorder that has been mis diagnosed for 40 years by over 100 doctors now and I have to tell you every one of the people claiming this have sounded quite anxiety filled. Like me the answer is still unknown and panic has taken over. I have been there many times in pain. I am not denying anyone is suffering. And I am not discounting anything. Just without more proof I am not blindly blaming marijuana. Even if stopping it helped. I think there is a related or underlying cause. Like cigar smoking tons of nicotine and smoking high thc weed and blaming only the weed even if the action together is the actual cause. Or even a hormonal or mental aspect involved. If it is real information will continue to surface and eventually we will know.
