unsupervised accessibility of alcohol at home, having too much freedom and being left alone for long periods of time. Additionally, there is evidence that gender moderates the effect of family, school and peer factors on adolescent substance use. For example, some studies report that not living with both biological parents or having poor parent-adolescent communication is associated with substance use, especially in female adolescents. Main risk periods for substance use occur during major transitions in a child's life. Some of these transitional periods that could increase the possibility of youth using drugs are puberty, moving, divorce, leaving the security of the home, and entering school. School transitions such as those from elementary to middle school or middle school to high school can be times that children and teenagers make new friends and are more susceptible to fall into environments where there are drugs available. One recent study examined that by the time are seniors in high school, "almost 70 percent will have tried alcohol, half will have taken an illegal drug, nearly 40 percent will have smoked a cigarette, and more than 20 percent will have used a prescription drug for a nonmedical purpose” (Johnston et al., 2013). Binge drinking has also, been shown to increase once an individual leaves the home to attend college or live on their own. Most youths do not progress towards regular, heavy substance use after experimentation. Research has shown, when drug use begins at an early age, there is a greater possibility for addiction to occur. Three exacerbating factors that can influence substance use to become substance use are social approval, lack of perceived risks, and availability of drugs in the community. Youths from certain demographics are also at higher risk for addiction. These groups include those suffering from a mental illness and who comes from a family history of addiction. Yet, some teens living with dual diagnosis prove that there is not always a causal relationship between mental illness and a substance use disorder. Moreover, when addiction occurs, youth are more likely to require teen rehab as a form of treatment. Most young adults have a false perception that they may be invincible. These individuals believe changes won't be made until an extreme event happens i.e. a friend overdoses, a car accident or even death. Even then it is not likely that they will see the correlation between use and trauma. Substance use
