Who wants you to smoke? “…the cigarette for the beginner is a symbolic act, it says ‘I am no longer my mother’s child. I am tough, I am an adventurer, I am not a square’… as the force from the psychological symbolism subsides, the pharmacological effect takes over to sustain the habit.” Philip Morris (Tobacco manufacturer) 1978
What Is In A Cigarette? Filter Paper Tobacco
Lungs The tar in cigarette smoke damages cells in the airways of your lungs. Eventually this damage can produce cells that grow uncontrollably - leading to cancer of the lung or voice box (larynx).
Heart From the moment smoke reaches your lungs, your heart is forced to work harder. Your pulse quickens, forcing your heart to beat an extra 10 to 25 times per minute, as many as 36,000 additional times per day.Because of the irritating effect of nicotine and other components of tobacco smoke, your heartbeat is more likely to be irregular. This can contribute to cardiac arrhythmia, and many other serious coronary conditions, such as heart attack. A recent Surgeon General’s report estimated that about 170,000 heart attacks each year are caused by smoking.
Blood Vessels Smoking increases your risk of vascular disease of the extremities. Severe cases may require amputation. This condition can produce pain and can increase your risk of blood clots in the lungs.
Skin Smoking constricts the blood vessels in your skin, decreasing the delivery of life-giving oxygen to this vital organ. As the result of this decrease in blood flow, a smoker’s skin becomes more susceptible to wrinkling.

The Cost of Smoking…to the World “Over 200,000 hectares of forest are cut down and burnt every year to ‘cure’ the tobacco. That’s 2 million square km a year. Tobacco production also poisons soil that could be used for food crops in developing countries” Source: ash.org.uk

The situation in Spain “It is illegal in Spain to traffic cannabis or to smoke it in public places. It is legal in Spain to cultivate or smoke cannabis for your own personal use (as long as it is in the privacy of your own home).” Source: http://gospain.about.com/od/drugsinspain/f/is_cannabis_legal_in_spain.htm
Cannabis is illegal in the UK It was downgraded from a Class B to a Class C drug in January 2004. Cannabis is still illegal. The maximum sentence for possession is the same as other Class C drugs, but the maximum prison sentence for supplying it remains at 14 years - the same as other Class B drugs.
Why is cannabis illegal in the UK? Cannabis smoke contains chemicals which may cause mental illness in some people. There are 400 chemicals in marijuana smoke. 60 of these have been proven to cause cancer. These chemicals can stay in the body for months or even years. Also, marijuana contains THC, a “neurotoxin” (a poison that damages nerves.) Cannabis intoxicates the mind and blurs your judgement compared to cigarettes.
The rest of the world “Recreational marijuana use has long been the subject of heated debate. In some countries smoking weed can come at a heavy price, ranging from execution (United Arab Emirates) to a few years in prison (Japan). Other countries, for instance Canada, see less harm in an occasional joint and allow their citizens to possess small amounts of cannabis” Source: http://www.huffingtonpost.com/2012/11/20/world-marijuana-laws_n_2167537.html
