” According to the National Institute on Drug Abuse, „Studies show that someone who smokes five joints per week may be taking in as many cancer-causing chemicals as someone who smokes a full pack of cigarettes every day.” Marijuana contains more than 400 chemicals, including the most harmful substances found in tobacco smoke. For example, smoking one marijuana cigarette deposits about four times more tar into the lungs than a filtered tobacco cigarette. […] The short-term effects are also harmful. They include: memory loss, distorted perception, trouble with thinking and problem solving, loss of motor skills, decrease in muscle strength, increased heart rate, and anxiety. Marijuana impacts young people’s mental development, their ability to concentrate in school, and their motivation and initiative to reach goals. And marijuana affects people of all ages: Harvard University researchers report that the risk of a heart attack is five times higher than usual in the hour after smoking marijuana.”
Marijuane jak wszyscy wiedza pali sie bez filtra a papierosy z filtrem.
