What are the potential dangers of using marijuana?
Heavy or chronic marijuana addiction may cause lung disease, more quickly than tobacco smoking. Marijuana may also raise blood pressure and affect short-term memory. At high doses, marijuana can be almost as powerful in its effect on the brain as hallucinogenic drugs. Heavy users may experience distortions in their sense of the passage of time, as well as hallucinations, loss of control of muscle movement, and a sense of detachment from his/her surroundings.
