Frequently Asked Questions
Is Marijuana addictive?
The definition of addiction is “A compulsive physiological and psychological need for a habit-forming substance”. It is possible to develop a psychological addiction to most things that are taken to excess, however cannabis is not physically addictive, although it is accepted that in some cases a psychological dependence can occur in heavy to chronic users. Among marijuana users it is relatively rare, although few users develop dependence, some do.
According to the National Academy of Sciences’ Institute of Medicines 1999 report, Marijuana and Medicine: Assessing the Science Base: “Compared to most other drugs dependence among marijuana users is relatively rare, although few marijuana users develop dependence, some do.
But they appear to be less likely to do so than users of other drugs (including alcohol and nicotine), and marijuana dependence appears to be less severe than dependence on other drugs.” Even heavy cannabis users wont suffer withdrawal as is the case with alcohol, hard drugs and prescription medicines.
Chronic users who stop using cannabis report experiencing irritability, restlessness and find it difficult to sleep for at least a week after discontinuing use.
Does using cannabis lead to harder drug use?
There is no evidence that cannabis leads to hard drug use. According to the National Academy of Sciences’ Institute of Medicines 1999 report, Marijuana and Medicine: Assessing the Science Base:
“There is no conclusive evidence that the drug effects of marijuana are causally linked to the subsequent abuse of other illicit drugs. There is no evidence that marijuana serves as a stepping stone on the basis of its particular physiological effect.”
Is marijuana more dangerous than tobacco?
Cannabis is not more dangerous than tobacco. Research shows that daily cannabis smoking does not lead to increased rates of respiratory illness.
Unlike tobacco, research has never shown that cannabis increases rates of lung cancer or other cancers usually associated with cigarette smoking. In May 2006, Dr. Donald Tashkin of UCLA presented results of a new study showing that even chronic marijuana smokers had no increased risk of lung cancer.
What are the different strains of cannabis?
There are three distinct types of cannabis plant that are grown for their psychoactive content.
These are Cannabis Indica, Cannabis Sativa and Cannabis Ruderalis.
The fourth classification is given to what is now referred to as Hemp, this is the name given to non psychoactive cannabis plants that are grown commercially for seeds, oil and fiber.
These plants typically contain around 3% THC content, however, hemp strains have been artificially bred to contain very little cannabinoid content to satisfy the prohibition lobby.
In reality if farmers could grow regular cannabis they would be able to utilize more of the plant and earn extra income from the cannabinoids which could be used as medicine. This would effectively cripple the black market in cannabis as it would be so readily available.

Cannabis Ruderalis
This is a debated third variety of cannabis found in Russia, Poland, and other eastern European countries. Schultes classified Cannabis as having three species: Sativa, Indica and Ruderalis based on the formation of the seedpods. There is still some debate as to whether there is justification for this third category. Some features of Cannabis Ruderalis are large seeds, weedy plants around 150cm (5ft) tall and a lower level of THC than C. Sativas or C. Indicas.

Cannabis Indica
This variety originated from the mountainous regions of Central Asia. Local strains were collected from Kashmir, Pakistan, Northern India and Nepal during the early 1960's and these native plants became the gene pool for many of today's varieties. They are characteristically stocky and hardy plants that produce broad, maple like leaves and rarely reach heights in excess of 2m (7ft) outdoors, producing heavy, tight flowers that are high in psychoactive content.

Cannabis Sativa
These varieties originate from equatorial regions and can reach heights in excess of 4.5m (15ft). THey produce thin, spiky leaves and massive colas that are not very dense. Cannabis Sativa varieties are high in THC content and give the user a more profound and uplifting experience when compared to the more sedative effect experienced when using mainly indica varieties.
