“Legal statutes describe cannabis as a depressant with mild hallucinogenic properties, although it is also described as a stimulant and intoxicant. The effects of cannabis are a sense of euphoria, state of relaxation and enhancement of sensory experiences. The short-term effects of cannabis include an increase in appetite, faster pulse rate and impairment of both physical and intellectual performance. In large doses cannabis can cause effects similar to hallucinogens including confusion, restlessness, excitement and hallucinations. The long-term effects of cannabis may include the development of a tolerance for the drug and psychological dependence. According to research by Harvard University in the United States, the risk of a heart attack is five times higher than normal in the hour after smoking marijuana. Smoking marijuana also weakens the immune system and increases the risk of lung infections. Cannabis smoke has 50% more tar than smoke from regular cigarettes and contains more than 400 chemical compounds, several of which have been identified as carcinogens.”
