Marijuana Damages Brains in Young People

December 22nd, 2009 · No Comments

A new study, published in Neurobiology of Disease, states that daily consumption of marijuana (cannabis) in teens can cause depression and anxiety, and have an irreversible long-term effect on the brain.

According to Dr. Gabriella Gobbi, a psychiatric researcher from the Research Institute of the McGill University Health Centre, the damaging effects of marijuana on young brains are worse than originally thought.

“We wanted to know what happens in the brains of teenagers when they use marijuana and whether they are more susceptible to its neurological effects than adults,” stated Dr. Gobbi.

Her study points to an apparent action of marijuana on two important compounds in the brain — serotonin and norepinephrine — which are involved in the regulation of neurological functions such as mood control and anxiety.

Marijuana Worse Than Tobacco Cigarettes For Lung Cancer Risk

February 9th, 2008 · No Comments

cigarette-rollsSmoking a joint is equivalent to 20 cigarettes in terms of lung cancer risk, and scientists have warned of an “epidemic” of lung cancers linked to cannabis (marijuana).

In an article published in the European Respiratory Journal, the scientists said cannabis could be expected to harm the airways more than tobacco as its smoke contained twice the level of carcinogens, such as polyaromatic hydrocarbons, compared with tobacco cigarettes.

The method of smoking also increases the risk, since joints are typically smoked without a proper filter and almost to the very tip, which increases the amount of smoke inhaled. The cannabis smoker inhales more deeply and for longer, facilitating the deposition of carcinogens in the airways.

Marijuana addiction is becoming a real problem.

Marijuana is the most frequently used illegal substance in many countries, including the United Kingdom and the United States and it seems to increase the chance of becoming psychotic, researchers report in an analysis of past research that brings up the old issue of whether pot is dangerous.

The new review suggests that even infrequent use of marijuana could raise the small but real risk of this serious mental illness by 40 percent.

Doctors have long suspected a connection and say the latest findings underline the need to highlight marijuana’s long-term risks. The research, paid for by the British Health Department, was published recently in the medical journal The Lancet. (thelancet.com)

“The available evidence now suggests that cannabis is not as harmless as many people think,” said Dr. Stanley Zammit, one of the study’s authors and a lecturer in the department of psychological medicine at Cardiff University.
