Re: Makes me nauseous!!!
In my experience no flavour by any company (other then couzzinz and king moassel) should make anyone sick. Instead I think that the problem is almost always related to the coals used so only use natural coals and make damn sure they are fully cooked before using. Other then that problems pretty much come down to how clean your rig is and how you smoke. Far too many people (most in fact) take deep inhales every few seconds which is sure way to get CO poisoning. Take it slow and shallow, and take a minute or two break every 10-20 minutes. Lastly don't smoke on an empty stomach and drink lots of anything non-alcoholic when you smoke.
Oh, I forgot to say that I have smoked all of the products mentioned by the OP and never had any issue with them.
