mation, I had to broaden my topic. I now understand which one is more dangerous and, for the most part, the long term affects. Through both animal and human testings, it has been proven that marijuana impairs lung functions to a greater extent than tobacco cigarettes do. But, this does not necessarily mean that marijuana users are putting themselves at more risk persay. Actually, a typical marijuana user will smoke maybe two cigarettes a day, whereas a typical tobacco-user will smoke between forty and sixty cigarettes in the same period. Now, the effects of the two have changed roles. Marijuana may have more tar in it, but at the usage rate in society today, tobacco-users put themselves at a much larger risks. Also, there is a chemical called benzopyrene that is 70% more abundant in marijuana than tobacco. This chemical is believed to cause and produce cancer. Tobacco has the same dangerous chemicals in it, yet the main one that it lacks that marijuana has is THC. THC, more specifically known as delta-9-tetrahydrocannabinol, is the drug that produces the "high" feeling that so many marijuana users become accustomed to. Marijuana usually does not contain more than 1 percent of THC. There are stronger drugs related to THC, such as "hash oil", which can contain up to a 28 percent THC level. There have been some cases where "street" marijuana has been found to contain up to 5 percent THC content. That is very potent for normal marijuana, and is probably very hard to come by in the United States. Other countries seem to use different forms of THC related drugs such as hashish, and hemp. Both of these contain more THC than marijuana. As far as long term effects of tobacco and marijuana go, they are about the same. Cancer should appear in the lungs of a tobacco-user earlier due to the amount the tobacco-user smokes in relation to a normal marijuana smoker. There have been many assumptions that marijuana will cause long term brain damage and...
