If I were to ask you if you would be willing to take a hit off of this knowing that there was a high percentage of chance that you would become addicted for life and a 50/50 chance that it would kill you would it make a difference if I called a slip or relapse?
We at whyquit.com and on the Freedom forum make no bones about calling it a relapse whether it be one puff or twenty cigarettes because it is what it is. If a heroin addict shot up just once, would that be considered a slip? If an alcoholic were to take just one shot of whiskey because he/she were out at a part acting silly would that be considered an acceptable risk? A slip is a euphemism meant to soften the implications of what someone has just done, eyes wide open.
If any of us were to smoke again or put nicotine back into our bloodstream through any delivery method, knowing what we know about addiction, I would call it an act of insanity or denial.
