Drug usage and addiction can affect an individual’s life to a large extent. However, near and dear ones of the substance abuser often witness a huge amount of behavioral change in them. Addiction is often perceived to be a disease or condition which not only affects an addict but also everyone around him or her. Sometimes, traumas are created in various relationships profoundly, because of the addictions. An addict is likely to focus on the drug consumption solely, thereby neglecting various other aspects and relationships of his or her life. Obtaining drugs is the primary priority of the addicts. It can actually trigger various types of emotions amongst the family members when an addict indulges in consumption of a drug. For example, they can oftentimes, feel bitter, resentful, and jealous or hurt due to the distorted behavior of the addicts. On the other hand, addiction can be one of the most significant causes of the financial troubles. Most of the times, the addicts purchase even more drugs to satisfy their gluttony. At times, the degree of addition can be extremely high thereby making an individual non-performer, in the workplace. One can easily spend a large amount for fueling the habit of consuming drugs. Hence, it will be elucidated in this paper how an individual who indulges in an excessive consumption of alcohol or other substances often impacts his family as well. Apart from all these things, another sociological concept will also be put to use so as to dissect this topic lucidly. 
Discussion 
A plethora of symptoms can be witnessed by the family members of a substance abuser. For example, an addicted person can lose his relationships all together. He can also separate himself from all the nearest people thereby losing interests in the daily-life activities. As a result, this very separation can prove to be extremely painful later on because he may ultimately lose his wife or best friends. On the contrary, the friends and family can actually encounter several negative emotions and mindsets, due to the loved one’s addiction. At times, they can end up blaming themselves instead of finding the real reason behind this instance. Moreover, addiction fosters mistrust, largely. Anxiety and depression are the two main negative consequences evident for the family members. Contradictorily, the caretaker role can be embraced by the family members without any prior signals. Several diseases, illnesses and the disorders often manifest as the blood streams of the addicts often toxify in the addictions. Caretaking can prove to be a big burden for the members of family thereby disrupting their own lives, both professionally and personally (Orford, Velleman, Natera, Templeton & Copello, 2013). Their needs are neglected in this way. When a person indulges in enabling, she or he can contribute to the substance usage of the addicts.  An addiction often burns big holes in the pockets. The persons’ drug usage can often surge, which is compulsive and frequent in nature. A person can end up losing his or her job because of the addictions. Oftentimes, the addicts steal money from their own houses. Thus, the family members may stop trusting that person. It disrupts the balance of a family’s function. Drugs and alcohol can be the catalyze of change in the peoples’ brain structure. For example, an addicted person hardly has any inhibition in himself. He can start to take more number of risks. Even an alteration in the way an addict reasons can be observed explicitly as well. Hence, both the aggressive and violent behaviors are noticeable when an addict loses his or her inhibitions. For example, an abuser can physically, verbally, or sexually assault others; these types of behaviors can often be projected towards a child or spouse (Rowe, 2012). Last but not the least, certain drug addictions lead to fatal diseases. For example, both meth and heroin carry the risks of potentially serious and deadly diseases that are actually transmissible. Hepatitis C, HIV, and Hepatitis B are the commonest of diseases found amongst a particular cluster of drug users. Once more, less of inhibitions lead to usage of dirty needles which channelize towards risky behaviors. Thus, the transmissible diseases increase the physical vulnerability of the affected addicts’ family members. Even accident rates are also high amongst the alcohol drinkers. It not only leads to the accidents of family members, who accompany them but also often the same reduces an addict’s quality of life. Apart from these, one must understand that bringing all the family members in a single table, for discussion is difficult. Mutual understanding is called for the same. The chances are high that the understanding will lead to adjustments and flexibility in the near future (Baldwin, Christian, Berkeljon & Shadish, 2012). Alternatively, the counselors of substance abuse cannot afford to focus merely on the needs of a patient. A holistic approach is required for the same. Thus, the family members are invited to resolve the emotional and physical condition of an addict. 
The systems theory used in the sociology deals with the study of complex elemental arrangements where both the individuals and their various belief systems remain involved. In fact, the concept has been used for several years (Bausch, 2012). The theory proclaims that the already complex society is continuously, evolving and reaching a state of perfection. Structural differentiation is extremely evident in the case of societal evolution. As per one of the perceptions, the social systems stabilize without any rational plan (Straussner, 2012). On the contrary, another theory argues that the society is mostly an organism, revolving which several developments take place, for its survival.
Usually, the systems theory supports the aspect of groups and their impacts on the individuals’ lives. After all, the human beings dwell in a nested system of the society. Some of the components included in the nested social systems are the organizations, families, societies, neighborhoods, and cultures. Both the group influences and individuals’ behaviors must be analyzed largely in order to understand and apply the theory in this paper. For instance, it is crucial to decode how the larger social systems influence the behavior of addicts. Everyone should equally maintain peace and order in the society so as to improve the functions of the society (West & Brown, 2013). As a result, it is observable how the participation of every individual is substantial for maintaining the societal order. The main system of interest, in respect to the addiction is the family cluster. Families mostly operate for maintaining the balance, like all other systems prevailing in the society. Generally, it entails all the pressures and activities to avoid the hostility, conflicts, aggression, and many more things (Monti, Colby & Tevyaw, 2012). All these things often lead to disharmony. It can be quite exhausting to maintain this peace and balance. As a result, whenever a person tries to discontinue his own addiction of drugs or any other substances, various family members may get affected by the same. Thus, in simple words, it can be said how the recovery process is actually more of rocking a boat. For example, the recovery procedure can include the family systems’ evaluation in regards to the family therapy. Often these forces encourage the addictions to boom. However, only when such a system is recognized, the family members come together to work out and produce a more functional system of the family.  For instance, a single lady can drink alcohol all by herself, in the evening, after a stressful day at work. Moreover, she is burdened with the pressure to raise all the four children by herself. Therefore, a system approach can suggest the single women to marry for the second time and share her responsibilities, if possible. It may not be practically possible in all the instances and that is why, other substitutes can come to the forefront. The woman can eat and sleep with her children so that they get more time together, which can relieve some of her lonely feelings as well. 
Interestingly, the traditional nuclear families were different from the ones that exist in this era. For instance, a significant surge can be witnessed in different types of the family structures such as the blended families, single-parent homes, and grandparent-headed families. Therefore, it cannot be denied that each of these systems can affect the individuals of the families in a segregated manner. Age is another determinant of the substance abuse (Kaminer, 2013). Most importantly, each situation of addition is different because of the distinction amongst the family norms and systems.  There is a universal causal link between the family functioning and substance abuse. It can be noted how the overwhelming addictions are mainly negative in nature (Feinberg, Solmeyer & McHale, 2012). The family roles shift naturally, to align with the associated new behaviors. The behaviors are mostly related to the alcohol usage and drugs. 
The children raised by the alcoholic parents are likely to grow up as the alcoholics than their counterparts. A tragic cycle revolves around the substance abuse and the domestic fights. For example, the number of domestic-abuse cases is largely related to the use of excessive alcohol or drugs. Both the victims and abusers consume substances adequately. A traumatized child can take refuse in various substances. On the other hand, an abuser can throw a child towards a traumatized life by beating him up, out of mere aggression caused due to addiction (Lander, Howsare & Byrne, 2013). Thus, it is a vicious circle. Hence, the family members are taken into account while treating an addict via the application of different psychological theories. 
Conclusion 
It can be inferred from the above-discussion that the substance abuse impairs both the mental and psychical health. People are largely nested in a varying number of systems, as per the ecological perspective. For example, the families operate within the communities while the individuals are often part and parcel of those families. Systems theory is one of such models in sociology which dissect the family ecosystem and substance abuse concept. Thus, the therapists and psychologists often encourage and suggest a sparing family participation for treatment of the addicts. After all, the family members are the first ones to get impacted by the disruptive and inappropriate behaviors of the substance abusers.
