The progression to drug dependence.

Here is a more detailed description of each stage:

Experimentation: In the experimentation stage, people try drugs out of curiosity or for social reasons. They may be curious about the effects of the drug, or they may feel pressure to use drugs from their friends. They may also use drugs to cope with stress or negative emotions. At this stage, people are not usually addicted to the drug, but they may be at risk for developing a problem if they continue to use it.

Regular use: In the regular use stage, people use drugs more frequently and may start to experience some negative consequences, such as problems at work or school, or relationship problems. They may also start to develop a tolerance for the drug, meaning they need to use more of it to get the same effect. At this stage, people may be starting to develop an addiction to the drug, but they may not be fully aware of it yet.

Addiction: In the addiction stage, people are physically and psychologically dependent on the drug. They may experience withdrawal symptoms if they stop using the drug, and they may be unable to control their drug use. They may also start to neglect their responsibilities at work or school, or in their relationships. At this stage, addiction is a serious problem that can have devastating consequences for the individual and their loved ones.

If you or someone you know is struggling with drug addiction, it is important to seek help. There are many resources available to help people overcome addiction and regain control of their lives.

here is a page describing the three stages of progression to drug dependence:

2. Regular use: This is the second stage, where people use drugs more frequently and may start to experience some negative consequences, such as problems at work or school, or relationship problems. They may also start to develop a tolerance for the drug, meaning they need to use more of it to get the same effect.
3. Addiction: This is the third and final stage, where people are physically and psychologically dependent on the drug. They may experience withdrawal symptoms if they stop using the drug, and they may be unable to control their drug use.
