The cannabis plant's flowers contain a chemical or drug known as THC (short for tetra-hydro-cannabinol). Smoking or eating the flower can make a person feel euphoric (very good) or sleepy. The plant is also used to make hemp fibre, and for its seeds and seed oil.
In its natural environment, THC's purpose was to protect itself against being eaten. There are many varieties of cannabis, and those low on THC production are selected for producing hemp and seeds.
Ancient history[change | change source]
Scientists believe that cannabis first grew somewhere in the Himalayas. Evidence of people smoking cannabis goes as far back as prehistory: archaeologists have found burnt hemp seeds at a burial site in what is now Romania. The most famous users of cannabis were the ancient Hindus, who called it ganjika in Sanskrit (ganja in modern Indian languages). According to legend, the Indian god Shiva told his followers to worship the plant. The ancient drug soma was sometimes associated with cannabis.
Cannabis was also known in ancient Greece, where magicians would burn its flowers in order to cause strange thoughts in the audience members' minds. Historians think that the cult of Dionysus also began in ancient Greece and involved inhaling cannabis smoke.
Effects[change | change source]
When a person inhales cannabis smoke or consumes cannabis, he or she may get a feeling called "getting high" or "getting stoned". Cannabis's most common effects include feeling happy, relaxed, tired, silly or scared; having many ideas about what to do; not being able to think clearly (or remember some things at all); and getting hungry (also called getting "the munchies"). Smoking cannabis changes how people think and feel, making it either harder or easier to solve some problems. Some people who take cannabis feel strange or paranoid (worried that something bad is going to happen).
Hashish (dried resin) is much more concentrated than cannabis (it includes both leaves and flowers). Because of this, people who take large amounts of hashish may feel even stronger effects. They may also see things or hear things that do not exist (these are called hallucinations). They may also have strange thoughts. Some hashish users like the feeling of these visions and thoughts, while others may find them scary. However, people rarely get hallucinations after smoking or eating cannabis.
Legal status[change | change source]
Personal use[change | change source]
On December 11, 2013, Uruguay was the first country in the world to make it legal to grow, sell, and use cannabis. Other countries that allow people to have small amounts of cannabis (just enough for them to use personally) include Colombia, Ecuador, Jamaica, the Netherlands, Peru, Portugal, Spain, and Switzerland. In the United States, on January 1, 2014, the states of Washington and Colorado made it legal for people aged 21 or older to buy cannabis.
Medical cannabis[change | change source]
As of 2016, many different countries and some states in the United States have made it legal for people with certain medical problems to use cannabis as a medicine. Medical use of cannabis is legal in Austria, Belgium, Canada, Chile, Colombia, the Czech Republic, Finland, Israel, the Netherlands, and Spain.
According to a 1999 report by the Institute of Medicine, cannabis (especially THC) can decrease pain; control nausea and vomiting; and improve appetite. As of June 2016, according to the National Conference of State Legislatures, "Further studies have found that cannabis [helps] some of the symptoms of HIV/AIDS, cancer, glaucoma, and multiple sclerosis.
Dangers of cannabis[change | change source]
Cannabis is one of the least dangerous of the commonly used illegal drugs. It is almost impossible to overdose on cannabis. A person would have to smoke their entire body weight in five minutes in order to overdose.
It is a common belief that people who use cannabis are less interested in life and may not want to go to school or work (scientists call this "amotivational syndrome"). However, many reports show that people who use cannabis do just as well as non-users.
Driving while "stoned"[change | change source]
A person who is intoxicated ("high" or "stoned") from cannabis could get hurt or killed in an accident if they drive a car. It is not safe to drive under the influence of any intoxicant. However, drivers who are "stoned" are much less likely to get into car accidents than drunk drivers and in some cases, sober drivers.
Addiction[change | change source]
"Hard drugs", such as heroin, meth, and cocaine, are chemically addictive. This means that if a person starts taking heroin, meth, or cocaine, that person's body will physically need to keep taking the drug. If they try to stop using the drug, they may become very sick. Cannabis and hashish are not chemically addictive, but they can be psychologically or habitually addictive. This means that people can get so used to the pleasure cannabis causes that they feel as if they need the drug. Unlike with alcohol, tobacco, and hard drugs, most people who use cannabis can stop taking it when they want, while experiencing only minor withdrawal symptoms. However, while cannabis may not be as addictive as other drugs, people can still become very much addicted to the pleasure of cannabis.
