Which behavior indicates a higher level of nicotine dependence?

Using tobacco immediately upon waking is a strong indicator of higher nicotine dependence. This behavior suggests that the individual has developed a significant habit surrounding nicotine consumption. Nicotine is known to produce withdrawal symptoms when an individual goes without it for an extended period, and using tobacco first thing in the morning often reflects a physical and psychological craving that can only be satisfied by immediate use.

Individuals who wait to use tobacco, such as 30 minutes after waking, may be showing lower dependence. In contrast, smoking just five cigarettes a day might indicate less frequent use rather than a high level of dependence. Accidentally swallowing tobacco juice while chewing does not directly relate to typical dependence measures and may instead reflect a lack of experience or control rather than established addiction. Thus, the behavior of using tobacco first thing in the morning is the most telling sign of significant nicotine dependence.
