Types of Addiction
The substances that constitute the majority of human addictions are categorized as follows:
1. Addiction to narcotic drugs: opium, heroin, morphine, hashish, cocaine, LSD, etc.
2. Addiction to other substances (non-narcotics): cigarettes, alcohol, and soporifics.
3. Addiction to stimulants: amphetamines, coffee, cocoa, tea, etc. Of course, these types of addictions are not real addictions in the conventional sense, but due to constant consumption, continuous repetition, and the inability to stay away from them, a kind of tendency and desire is created for these effective substances, which are used to stimulate the nervous system, relieve weakness and nervousness, as well as relieve fatigue and increase the general activity of the body.
Classification of Addictive Substances
Various divisions have been proposed for addictive substances, which have been made considering the characteristics of those substances. For this topic, the division is based on different criteria; perhaps it can be claimed that the best division is:
1. Opioids (Hypnotics): This category includes substances such as opium and heroin, which have hypnotic and soothing effects.
2. Hallucinogenic Substances: These substances cause changes in feeling, perception, cognition, judgment, and will. Among these substances, we can mention hashish, marijuana, mescaline, etc.
3. Stimulant Substances: This category includes substances such as cocaine, amphetamine, and nicotine that increase physical and mental activity.
4. Sedative Substances: These substances include alcohol and barbiturates, which have sedative and soothing effects.
Stages of Addiction
In general, the stages of addiction can be divided into three stages:
1. Acquaintance and Initiation: In this stage, based on curiosity, imitation of others, or an effort to relieve pain, a person becomes familiar with drugs and starts using them.
2. Ambivalence and Doubt: After starting to use drugs, despite the anesthetic effects of those drugs, the user feels guilty, and a feeling of hesitation and doubt develops for the user.
3. Addiction: In the third stage, as a result of repeated use, physical and mental dependence on the addictive substance develops, and the person becomes addicted.
