What Is the Thesis Statement of This Paragraph?

Question by leona2000: What is the thesis statement of this paragraph?
I have to critique an informative essay and this is the first paragraph. What is the thesis statement, please?

In recent times, many researches have been conducting on therapy and treatment options available for people who are substance (drugs and alcohol) abusers, and these have come a long way from the older treatment options (e.g. Glasscote et al, 1972). These observations have led the researchers to believe that drug addiction and alcoholism are not just primarily a physical ailment but it is also complemented heavily by environmental factors. Alcoholics and drug abusers tend to follow a specific pattern and we find that many of the people who have alcoholic tendencies come from their genetic makeup (Crabbe, 2002). Yet, even though there are some genetic influences that come into play, the abuse is fed by the abuser’s immediate environmental factors, such as the attitudes of the family, friends, and support groups. The genetic side of this ailment explains how there are metabolic, structural, and neuro-chemical malfunctions in the brain that causes a person to become addicted to the drugs, which are supplemented by the environmental factors such as the various home, psychological, and social dynamics that the person experiences in his or her life. These two factors are bi-directional, which means that they both interact and conflict with each other in making the symptoms of alcoholism stronger in a person.

At the risk of doing your homework for you. It is the last sentence. Typically the thesis statement is at the very last of the opening paragraph.

Answer by Reginald G
I think it is found in this sentence, if we change the first word to modern.

Modern observations have led the researchers to believe that drug addiction and alcoholism are not just primarily a physical ailment but it is also complemented heavily by environmental factors.

Put briefly, it would be “Drug addiction and alcoholism are a result of both nature and nurture”.
