Marijuana: Effects of Weed on Brain and Body
Marijuana is a combination of shredded leaves, stems and flower buds of the Cannabis sativa plant. Marijuana can be smoked, eaten, vaporized, brewed and even taken topically, but most people smoke it. The intoxicating chemical in marijuana is tetrahydracannabinol, or THC. According to research from the Potency Monitoring Project, the average THC content of marijuana has soared from less than 1 percent in 1972, to 3 to 4 percent in the 1990s, to nearly 13 percent today.
A history of New Zealand's recreational drug use
In New Zealand, we do heaps of drugs. Nearly half of us have used illegal substances at some point in our lives. In fact, a few years ago, a British medical journal's study found New Zealand and Australia had the highest rate of cannabis, meth and ecstasy use in the world. So how did we get here? Before Europeans arrived, Maori didn't really use drugs.

Marijuana use can lead to the development of problem use, known as a marijuana use disorder, which takes the form of addiction in severe cases. Recent data suggest that 30 percent of those who use marijuana may have some degree of marijuana use disorder.18 People who begin using marijuana before the age of 18 are four to seven times more likely to develop a marijuana use disorder than adults.19 Marijuana use disorders are often associated with dependence—in which a person feels withdrawal symptoms when not taking the drug. People who use marijuana frequently often report irritability, mood and sleep difficulties, decreased appetite, cravings, restlessness, and/or various forms of physical discomfort that peak within the first week after quitting and last up to 2 weeks.20,21 Marijuana dependence occurs when the brain adapts to large amounts of the drug by reducing production of and sensitivity to its own endocannabinoid neurotransmitters.22,23
Has alcoholism become New Zealand's accepted addiction?
As you can see, New Zealanders now consume less alcohol per capita than many other countries, but everyone over the age of 15 is still drinking 8.7L of alcohol here each year. Russia is the reigning champion of alcohol consumption, with a per capita swig of 13.8L, while our friends in Australia, the UK and US are all drinking in greater amounts than we are. Kiwis used to have the reputation of being heavy drinkers – and perhaps we still do. We certainly love a tipple or two, but our tastes have gone from enjoying three or four mass produced beer brands in the 1960s to producing and consuming some of the best wines, craft beers and vodkas on the planet.
Cannabis
La cannabis sátiva: es una planta que puede llegar a medir unos seis metros de altura en las condiciones más favorables; es un vegetal dióico, es decir, que tiene plantas macho y hembra que crecen por separado. En ambientes húmedos segrega una gran cantidad de resina, que las hace pegajosas al tacto, por lo que se dice que puede ser un mecanismo de defensa frente a la humedad ambiental. El sexo de la planta se diferencia por el examen de las flores, las masculinas pueden apreciarse a simple vista y se agrupan en racimos, y las femeninas son casi invisibles y se agrupan en espigas. El fruto "cañamones", tiene forma globular, de unos cinco milímetros de diámetro, que se emplea para la alimentación de las aves, y para la extracción de aceite.
