Blood flow is actually increased to the frontal lobes and lateral cerebellum. Heavy marijuana users often can continue to have subtle defects in cognitive tasks up to one day of abstinence (Solowij 2119). The effects of long-term use on the intellect are unknown, and evidence that marijuana induces or causes brain damage does not exist (Marijuana 1). The one thing marijuana does impair is the psychomotor performance. This can include body sway, hand steadiness, rotary pursuit, driving and flying simulation, divided attention, and sustained attention. Like alcohol intoxication, marijuana intoxication impairs judgment, comprehension, memory, speech, problem ability, and reaction time. This is why it is very dangerous to operate heavy machinery or drive while intoxicated by marijuana or alcohol. But there are laws on how much can be consumed while driving. Overall, very little or no evidence is shown to prove that marijuana has harmful effects psychologically.
Also the use of marijuana is said to cause motivational syndrome, which means dropping out of social activities, or the lack of interest in school, work, or goal-related activities. While many people who have traits of the so-called AS may use marijuana, marijuana is not the cause of their behavior (Chait and Pierri 387). .
Ever since marijuana has become illegal, enforcing it has been an issue. The federal government of America spends millions of dollars each year trying to keep it off the streets and into dealer's hands, but their tactics barely do a thing. Today, 62% of all inmates are in prison for drug offenses the result of a 1,100% increase in drug arrests between 1980 and 1992, even though marijuana use dropped from 35% to 13% during the same period. Of felons convicted of crimes related to marijuana possession, production and trafficking during this period, 58% had no prior arrest history, 91% were not identified as organizers, leaders, mangers or supervisors of drug-oriented organizations, and 92% did not own or possess a gun(Schlosser 93).
