I smoke two packs of cigarettes a day and i want to quit. how can i do that without going to detoxification?

You have made: The first essential step...Saying you want to quit. Nicotine is addicitive, and a two PPD habit means you have may receptors begging to be fed. You can cold turkey, but are likely to fail. Next step, cut down to 1 ppd. Perhaps then .5 ppd, and then set a date. Cantix, nicoderm, (nicotine patch) and gum available to help if you ask.
