Drug abuse and addiction affects society in many ways; directly or indirectly, it is one major reason why juveniles and adults suffering from addiction are being incarcerated for committing crimes to support their drug or alcohol habit. Drug abuse and addiction are implicated in four out of five crimes committed by juvenile arrestees. Many teenagers in state juvenile justice systems are under the influence of alcohol or drugs while committing their crimes, test positive for drugs, are arrested for committing an alcohol or drug offense, admit having substance abuse and addiction problems, or share some combination of these characteristics.
In California alone an average of 1,000 people die each year from drivers high on marijuana and the numbers are expected to dramatically increase as more and more people are prescribed the drug. Medical marijuana users who drive under influence of what would now be considered a controlled drug have little or no repercussions in most states. The problem is there is no standard amount of THC allowed in the blood. Addiction Treatment admissions for marijuana have risen as much as 1/3 in states with medical marijuana laws.
