There are close to 90 million people who live within the United States  that are addicted to some form of narcotic or alcohol substance. This  means that 1 out of every 4 Americans will run the risk of being hooked  to some type of drug or some form of alcohol during their lifetime. One  way that the government, state and community organizations address this  issue is through the use of education. Education classes are made  available to the public and segments of the population that are at risk.  Preventing alcoholism or lowering the use of marijuana among teenagers  could be two goals for this type of instruction. Drug and awareness  classes help in addressing marijuana problem which can be a problem for  some children within different communities across the country.
 
 There are a variety of drug awareness classes that deal with the problem of marijuana. Most of these classes are made  available through local schools, hospital, mental health, community  centers and outreach programs. Many of the classes are targeted toward  teenagers and young adults since they are the most at risk portion of  the population when it comes to marijuana usage. It is estimated that at  least 5% of the population consistently uses marijuana on a daily basis  and at least 7% smokes this substance at least once per month.  Statistics also reveal that 1 out of every 12 adolescents between the  ages of 12-18 has access to marijuana. According to statistics provided  by the National Institute on Drug Abuse at least 42% of all high school  seniors tried marijuana at least one time before they reached age 18. It  is estimated that marijuana is most abused in high density college  states such as Arizona, and Massachusetts.
 
 When classes are taught to teenagers and adults issues such as the long  term impacts from marijuana use are addressed. Students are presented  with information about marijuana's affect on the human body and their  emotional states. Marijuana has been known to lead to anxiety attacks,  depression, schizophrenia and mental illness. Marijuana is also known to  place users at a greater risk for stress and violence. This drug  significantly increases the heart rate and could possibly cause a user  to die from cardiac related problems and it contains carcinogens which  irritate the lungs. This drug also interferes with a person's daily life  activities, their social stability and their ability to maintain  employment.
 
 Marijuana classes also instruct students about the medicinal aspects of  marijuana usage. Many people wrongly assume that it is okay to smoke  marijuana as long as it's for medical reasons such as in cases of  glaucoma and breast cancer. Most classes won't argue that this substance  can help to alleviate the problems associated with these conditions but  they're also quick to point out that marijuana usage might not be the  best way to deal with the symptoms associated with these medical  ailments. Younger people should also keep in mind that medicinal  marijuana is often made in the form of pills and not rolled and smoked  in the form of a "joint".
 
 Since these classes are designed to prevent marijuana use they usually  are free to the public. Many organizations are given grants and private  donations that goes toward sponsoring classes. Some classes might  require a fee and if they do it usually is relatively inexpensive to  attend.
