What would happens if i leave on the nicotine patch for longer than 24 hours?

Slow growth is good: The patch replaces the nicotine from smoking. The nicotine is mostly absorbed through the skin in 24 hours, so after that time very little nicotine is available. One day at a time works best. If you wean off very gently, and use mutual support, you may find that recovery is possible. Consider attending a meeting of nicotine anonymous.
