Marijuana

Overview Marijuana is a mind-altering (psychoactive) drug, produced by the Cannabis sativa plant. Marijuana contains over 400 chemicals. THC (delta-9-tetrahydrocannabinol) is believed to be the main chemical ingredient that produces the psychoactive effect.

Methods of abuse Marijuana is usually smoked as a cigarette (called a joint) or in a
pipe or bong. It is also smoked in blunts,  which are cigars that have been emptied of
tobacco and refilled with marijuana, sometimes in combination with another drug. Marijuana is also mixed with foods or brewed as a tea.

 

Effect on mind When marijuana is smoked, the THC passes from the lungs and into the
bloodstream, which carries the chemical to the organs throughout the body, including the brain. In
the brain, the THC connects to specific sites called cannabinoid receptors on nerve cells and
influences the activity of those cells. Many of these receptors are found in the parts of the brain that influence pleasure, memory, thought, concentration, sensory and time perception, and coordinated movement. The short-term effects of marijuana include problems with memory and learning, distorted perception, difficulty in thinking and problem-solving, and loss of coordination. The effect of marijuana on perception and coordination are responsible for serious impairments in driving abilities. Long-term chronic marijuana use is associated with Amotivational Syndrome, characterized  by apathy, impairment of judgment, memory and concentration, and loss of motivation, ambition and interest in the pursuit of personal goals. High doses of marijuana can result in mental confusion, panic reactions and hallucinations. Researchers have also found an association between marijuana use and an increased risk of depression; an increased risk and earlier onset of schizophrenia and other psychotic disorders, especially for teens that have a genetic predisposition.

 

Effect on body Short-term physical effects from marijuana use may include sedation, blood shot
eyes, increased heart rate, coughing from lung irritation, increased appetite, and decreased blood
pressure. Like tobacco smokers, marijuana smokers experience serious health problems such as
bronchitis, emphysema, and bronchial asthma. Extended use may cause suppression of the immune system. Because marijuana contains toxins and carcinogens, marijuana smokers increase their risk of cancer of the head, neck, lungs and respiratory track. Withdrawal from chronic use of high doses of marijuana causes physical signs including headache, shakiness, sweating, stomach pains and nausea, as well as behavioural signs including restlessness, irritability, sleep difficulties and decreased appetite.

 

Drugs causing similar effects Hashish and hashish oil are drugs made from the cannabis plant
that are like marijuana, only stronger. Hashish (hash) consists of the THC – rich resinous material
of the cannabis plant, which is collected, dried, and then compressed into a variety of forms, such
as balls, cakes, or cookie like sheets. Pieces are then broken off, placed in pipes or mixed with
tobacco and placed in pipes or cigarettes, or smoked. The main sources of hashish are the Middle
East, North Africa, Pakistan and Afghanistan. Hashish Oil (hash oil, liquid hash, cannabis oil) is
produced by extracting the cannabinoids from the plant material with a solvent. The colour and
odour of the extract will vary, depending on the solvent used. A drop or two of this liquid on a
cigarette is equal to a single marijuana joint.

 

Overdose effects No death from overdose of marijuana has been reported.
