Nicotine takes much longer to reach peak brain levels in smokers, contradicting traditional puff-by-puff spikes, and may depend on overall rate of accumulation, habit, and sensory cues. Smokers who eventually experience high nicotine levels without becoming addicted still lack clear explanations for their non-addictive status.
