There has been a dramatic increase in the use of marijuana since 1992. Nationally, 47% of college age people have used marijuana in the past year. 20% have used in the last month. 4% use it on daily basis. In 1997 here at Rutgers, we found that 70.8% of students never used marijuana during that past year. 15% used it less than once a month. 7.9% used it one or two times a month. 2.2% used it once a week. 2.7% used it two to three times a week. Finally, 1.4% used marijuana on a daily basis.

What is Marijuana?

Marijuana is a green-brown mixture of dried and crushed leaves from the hemp plant (Cannabis sativa), which looks like dried parsley leaves mixed with stems and /or seeds. It is usually rolled up into a cigarette, called a joint or a blunt, and smoked, but it can be eaten.

Marijuana's main active chemical is THC (delta-9-tetrahydrocannabinol), which is found in all forms of cannabis that are psychoactive. The cannabis plant contains about 400 chemicals, but THC affects the brain the most.

What are the short term effects of using marijuana?

  • sleepiness and increased hunger
  • altered sense of time
  • impaired or reduced short-term memory
  • reduced ability to perform tasks requiring concentration and coordination, such as driving, or studying for an exam
  • increased heart rate
  • potential cardiac dangers for those with pre-existing heart disease
  • bloodshot eyes
  • decreased social inhibitions that can increase exposure to risky situations
  • risk of paranoia, hallucinations, intense anxiety, panic attacks

What are the long-term effects of using marijuana?

  • impairments in learning, memory, perception, and judgment
  • some people experience paranoia, hallucinations, intense anxiety, panic attacks- psychological dependence requiring more of the drug to get the same effect
  • paranoia
  • increased risk of chronic pulmonary disorders, including cancer (lung/mouth), emphysema, increase in testosterone levels for women
  • decrease in testosterone levels for men
  • lower sperm levels in men
  • increased risk of infertility in both men and women
  • diminishing or extinguished sexual pleasure
  • decreased social inhibitions and exposure to risky situations

How long does marijuana stay in the body?

The THC in marijuana is absorbed and stored in fatty body tissue, including the brain. THC shows unique specific reactions in the brain. It effects areas of the brain which are responsible for pleasure, smell, memory, movement and hormonal regulation. Because THC is stored in the fatty tissues and the concentration of THC varies, it is difficult to know the exact length of time it stays in the body. About half the THC is still in the blood 20 hours after smoking. Once the THC passes through the liver, it may stay in the body for days, affecting both mental and physical functions (even though youre no longer high). The breakdown products are slowly flushed out of the body and, although varied, traces of THC metabolites can be detected several days after smoking marijuana. In chronic users, remnants from THC may be detectable weeks after marijuana use. The same thing happens if you eat marijuana, except it takes longer to get to the brain.

How does marijuana affect driving?

Marijuana decreases attention and concentration (which is one reason why people use it). One study showed that young people who reported driving frequently while on marijuana were twice as likely to be involved in accidents. It seems that the marijuana-induced changes in perception and sense of time may be entertaining in the living room but can be deadly on the highway. Best bet: if you are using a psychoactive drug, do not drive or get into a car with someone who is. Marijuana affects all of the skills that are necessary to drive safely. The effects include diminished capacity to accurately judge distances, slower reflexes, and distorted perceptions of how fast you are going. Combined with alcohol, the hazards of driving under the influence of marijuana are far more extreme than with either drug alone.

Can a person become addicted to marijuana?

Addiction is a complicated process that is described by tolerance, dependence and withdrawal. Users can develop a tolerance over time. People who smoke marijuana or who have a genetic predisposition might develop a tolerance and would need more of the drug. Withdrawal can occur after chronic use and may be mild due to the THC lasting longer in the body because it is fat-soluble. Some people report irritability and restlessness and some have insomnia and nausea. People who use marijuana can become dependent when:

  • There is a constant desire for the high, or unsuccessful attempts are made to cut down or control use,
  • Too much time is spent getting high, taking away from other life activities,
  • Use is continued despite consequences like conflicts with, or loss of friends, family, or relationships; diminished academic motivation or performance; or negative effects on employment situation.

Heavy users however, can begin to show signs of dependence when they experience withdrawal symptoms. These symptoms include loss of appetite, problems sleeping, weight loss, and restlessness.

Why do people quit using marijuana?

People who quit using reported the following reasons: psychological damage, physical damage, dont feel like getting high, not enjoyable, partner disapproved

Can marijuana be used for medicinal purposes?

This is highly controversial. It does appear that there are some valid medicinal uses for marijuana.

Know the Facts

Marijuana is not harmless, as some would have you believe, although it may not be as harmful as other drugs that are now legal. The long-lasting effects on the brain and lungs are still unknown. Using marijuana remains illegal in the state of New Jersey.  You do not function normally and cannot do everyday activities which require concentration under the influence of marijuana.  Be aware of the risks. Using drugs increases the likelihood of unsafe sex, which can lead to unwanted sex, unintended pregnancy or sexually transmitted infections, and misunderstandings in relationships.  Keep your edge. Drug use can ruin your looks, make you depressed, and contribute to slipping grades.  Play it safe. One incident of drug use may make you do something that you may regret for a lifetime.  Using drugs puts your health, education, family ties, and social life at risk. Face your problems. Using drugs wont help you escape your problems; often only creates more.  Be a friend. If you know someone with a drug problem, be part of the solution. Urge your friend to get help. Call the Alcohol and Other Drug Assistance Program for Students (ADAPS) on campus.

Marijuana and New Jersey State Laws

Use or possession with intent to distribute, 0-10 years in jail, and a fine of $750 to $100,000.
