Which substance has the potential for both therapeutic and addictive properties?

Caffeine is primarily recognized as a stimulant with a low potential for addiction compared to other substances. It is widely used for its ability to enhance alertness and concentration, making it a staple in many people's daily routines. While it can result in mild dependence and withdrawal symptoms, such as headaches and fatigue, its addictive properties are generally viewed as less severe and disruptive than those associated with other substances.

On the other hand, substances like cannabis, benzodiazepines, and alcohol are well-documented for their therapeutic benefits while also having a higher potential for misuse and addiction. Cannabis has therapeutic uses for pain relief and anxiety but can lead to psychological dependence. Benzodiazepines are often prescribed for anxiety and insomnia, yet they carry significant risks of tolerance and addiction. Alcohol is commonly used socially and has recognized therapeutic uses, but it is also a well-known substance associated with addiction and severe dependence.

Thus, while caffeine has some therapeutic applications and can lead to a mild form of dependence, it does not exhibit the same level of addictive potential found in the other substances listed, making it less of a concern in this regard.
