It was not a good feeling to be among drug users. Although most appeared as normal as any healthy person, after a few minutes I found that something inside had been lost. The reasons for taking narcotics are varied: fun, a lack of parental love, pursuit of "fashion", low self-esteem, boredom and high levels of disposable income.

Maybe deep down, all human beings share the same feelings of weakness and powerlessness, especially when faced with temptations they can't resist on their own and choices they can't help making. Once addicted, only they can make the decision to clean up, but making the correct decision at the right time is tricky.

A trainer at the rehabilitation center told me she has heard many tragic stories about the dark side of human nature. Her own experience of drug addicts has also given her great empathy for the people she helps.
