What is Marijuana?

Marijuana is a green, brown, or gray mixture of dried, shredded leaves, stems, seeds, and flowers of the hemp plant (cannabis sativa). You may hear marijuana called by street names such as pot, herb, weed, grass, boom, Mary Jane, gangster, or chronic. There are more than 200 slang terms for marijuana. All forms of marijuana change how the brain works. They all contain THC (delta‐9‐ tetrahydrocannabinol), the main active chemical in marijuana. They also contain more than 400 other chemicals. People smoke, chew, or eat marijuana for its hallucinogenic and intoxicating effect. The strength of marijuana's effects on the user depends on the strength or potency of the THC it contains.

Effects of Marijuana

It is difficult to fully understand what the effects of marijuana might be because so many changes occur with use and there are even overlapping effects that involve different reactions in different body systems. The body systems are reacting to the THC, which triggers most of the mood and mind changes associated with the drug. THC is absorbed by fatty tissues in various organs.

Many users describe two phases of marijuana intoxication: initial stimulation - which includes giddiness and euphoria, followed by sedation and pleasant tranquility. Mood changes are often accompanied by altered perceptions of time and space. Thinking processes become disrupted by fragmentary ideas and memories. Many users report increased appetite, heightened sensory awareness, and general feelings of pleasure.

Most effects from changes in perception to feelings of relaxation and euphoria usually peak within an hour and disappear altogether in 2‐3 hours. Other effects may last longer. Since products from THC breakdown can linger in the body for days or weeks after use, hazardous activities or occupations can be risky.

Negative effects of marijuana use can include confusion, acute panic reactions, anxiety attacks, fear, a sense of helplessness, and loss of self‐control. Chronic marijuana users may develop amotivational syndrome characterized by passivity, decreased motivation, and preoccupation with taking drugs. Individuals who regularly use the drug may experience the same problems as tobacco smokers including cough, phlegm, chronic bronchitis, and frequent chest colds. In addition, because marijuana contains toxins and carcinogens marijuana smokers increase their risk of cancer of the head, neck, lungs, and respiratory tract. Like alcohol intoxication, marijuana intoxication impairs judgment, comprehension, memory, speech, problem‐solving ability, reaction time, and driving skills. The effects of long‐term marijuana use on the intellect have not been established.

Risks

Risks of use depend on where you are, who you are with, and what you are doing. Consider the following:

  • Marijuana can make it harder to function in school‐, work‐, or job‐related activities. Marijuana affects short‐term memory and brain cell transmission.

  • Marijuana slows reflexes and impairs visual perceptions.

  • On rare occasions, a person using marijuana can have a panic attack.

  • Marijuana directly affects the central nervous system.

  • Sex under the influence of marijuana carries risks too.

  • Smoking marijuana irritates the mouth, throat, and lungs.

  • Using marijuana can have legal consequences.

  • Marijuana use depresses the immune system and reduces lung capacity.

  • A positive drug test can result for days to weeks after using

    Since marijuana cultivation is illegal and THC levels are not standardized, you will never really know what you are getting. You also will not know what pesticides and other chemicals could have been used in growing it. Marijuana poses potentially serious risks to children, pregnant women, and those with underlying emotional problems.
