Nicotine can lead to addiction, whether it comes from cigarettes, vaping devices, smokeless tobacco, or nicotine pouches.
When nicotine and caffeine are used close together, it may become harder to tell which one is connected with restlessness, trouble sleeping, or feeling driven to repeat a routine. Your experience may also vary with timing, amount, health, medications, and other substance use, so an individual assessment is more useful than a universal rule.
