Injecting drugs meant they could take effect a lot faster. Cannabis cannot be dissolved in water, so it can't be injected.
Only recently have scientists began to scrutinize the chemical more closely, and have started to conduct clinical trials to test its medical effects.
Relief for multiple sclerosis sufferers
There are a total of 85,000 people suffering from multiple sclerosis (MS) in Britain. This incurable debilitating disease manifests itself with a host of symptoms:
balance problems
muscle weakness and spasms
incontinence
pain
tremors
Although pharmaceutical drugs are available to MS sufferers, the condition is difficult to control. Clinical tests performed by the Multiple Sclerosis Society showed that most patients responded positively to cannabis. The drug especially alleviated spasms, pain, tremor and increased bladder control.
In addition, a postal survey was conducted amongst patients self-medicating with cannabis in the UK and the USA. More than 90% reported a beneficial effect on their condition. Unfortunately, many patients end up obtaining cannabis illegally.
Is cannabis harmless?
Cannabis is less addictive than amphetamines, tobacco or alcohol, and does less harm to the body It may be psychologically addictive. Heavy users can display aggressive impulses if their supply suddenly stops, a side effect similar to that of anabolic steroids
A government report found that high use of cannabis isn't associated with major health or sociological problems, unlike other harder drugs Cannabis may be a 'gateway' drug to more harmful substances like heroin and cocaine
Its effects are beneficial to sufferers of various medical conditions, including cancer, HIV, multiple sclerosis, and glaucoma It has a higher tar content than tobacco, so smoking cannabis presents the same health problems: bronchitis, emphysema and lung cancer
Cannabis has an effect on the heart, similar to the effects of exercise. It may be just as good for the heart as going to the gym It can disrupt the control of blood pressure increasing the risk of fainting. Even occasional use is bad for people with heart and circulation disorders, and for those predisposed to schizophrenia
Origin of the species
The drug itself is derived from Cannabis sativa or Cannabis indica, a plant related to nettles and hops that grows wild in many parts of the world. Cultivation dates back thousands of years.
The first written account of cannabis use can be found in Chinese records dating from 2800 BC. However, experts widely accept that cannabis was being used for medical, recreational and religious purposes for thousands of years before that.
Cannabis plant
The plant is believed to have originated in the mountainous regions of India.
When left growing wild, it can reach a height of 5 metres and flowers naturally from late summer to mid autumn.
Customs estimate that up to 80% of cannabis resin entering the UK originates from Morocco and most smuggled supplies in its herbal form come from Jamaica. However, an enormous amount of cannabis these days is actually home-grown.
Legal high
Doctors have been allowed to prescribe capsules containing THC, the main active ingredient of cannabis, for years. Nabilone - a synthetically manufactured copy of THC - was licensed in 1982 for prescription use against nausea caused by chemotherapy.
THC molecule
However, some patients complain of the same side effect that many people state as the drug's main recreational attraction - it gets you stoned. Due to the complex relationship between THC and receptors in the brain, researchers haven't yet managed to separate the active medical ingredients from the brain-bending ones.
Cannabis aerosols
Patients taking the drug in capsule form are unable to control the dose as they can with careful inhaling. So the pharmaceutical industry has started developing THC aerosols and inhalers that don't harm lungs. This makes it easier for patients to control their dose and prevents them from getting too disorientated.

The dangers of driving, working or having unprotected sex after cannabis may be as significant as the drug's harmful effects on health, psychologists said yesterday.
Researchers at Birmingham University said policy makers overlooked the indirect dangers of smoking cannabis. In a study of 100 regular and 90 casual users, 74 per cent admitted driving under the influence of the drug.
A quarter of users said they had taken the drug before or at work, with just over half admitting that it had impaired their ability to do their job.
