Yes, you right it maybe not to bad or even helpful for some condition. But when you suffer and you don't know why like this guy, I suggest to avoid immunosuppressant stuff, things that can interfere with cortisol regulation and food known to trigger hypersensitivity. This is the best bet if you want to stabilize your condition. But if someone is having several addictions, I won't suggest to quite everything cold turkey. It may be too harsh on immnune, nervous and adrenal functions. I agree with you, I believe pot is not the worst sin.
