Marijuana is a rapidly growing shrub.  When ingested or smoked marijuana is a powerful psychoactive.  Marijuana is currently illegal.  Drugs that are more damaging to a person's health than marijuana are legal.  Enforcing marijuana laws is expensive.  The stigma attached to marijuana has social side affevts.  marijuana should be legalized.
Marijuana is not as damaging to a human's health as some legal drugs are.  In 2002 seventeen thousand people were killed in alcohol related auto accidents.  People that smoke cannabis are not as impaired as a drunk driver.  When an individual operates a vehicle under the influence of alcohol they will crash and potentially kill themselves, or someone else.  Cannabis smoke is less likely to cause cancer than tobacco smoke.  Smoker's of tobacco will get a variety of deadly cancers.  Most tobacco users will die of cancer at a relatively young age.  The human lungs contain nicotine receptors, but they do not contain THC receptors.  Lungs are not damaged by THC. On the other hand, nicotine is very poisonous and damaging to the lungs.  According to the prestigious European medical journal, The Lancet, "The smoking of cannabis, even long-term, is not harmful to health. ... It would be reasonable to judge cannabis as less of a threat ... than alcohol or tobacco."  there is no good reason for tobacco to be legal.  Cannabis is far more benign than tobacco.  Many legal drugs are more dangerous than marijuana.
Legalizing cannabis makes sense from an economic standpoint.  Enforcing marijuana prohibition costs taxpayers an estimated ten billion dollars annually.  We could spend this money on enforcing legitimate crimes such as theft, murder, rape etc.  Also consider that our nation is massively i debt, there is no reason that ten billion wasted dollars shouldn't be spent on alleviating financial strains on our government.  Marijuana costs less money than prescription pain pills such as Lortab.  If a cancer patient pays $10 a day for marijuana they are saving money over expensive pills.  When people save money they spend it which helps our economies.  Our economy needs this boost.
Teens that use cannabis are more socially active and healthier.   A Swiss study suggests that teens who use only cannabis appear to function better than those who also use tobacco, and are more socially driven and have no more psychosocial problems than those who abstain from both substances, according to a new report .  When teens use cannabis they will participate more in class than an a student that does not use cannabis.  If cannabis helps teens be more socially driven then why should it not be legal? One fifth of swiss cannabis users report having never used tobacco.  If cannabis were to be legalized tobacco use would plummet.  It is safer and healthier for kids to stay home and smoke weed than it is for them to go party, get drunk and get in a wreck driving home.   Teen sociality is sufferring and cannabis legalization would help.
It is rediculous for marijuana to be illegalized.  tobacco and alcohal are legal.  We spend money on marijuana prohibition.  Our children suffer from the lack of legalization of cannabis.  Marijuana illegalization is based in racism and communism.  There is absolutely no reason for marijuana to not be legal.
