can happen when you decide not to take marijuana. These are only the things that can happen on a short term. The things that happen on a long-term basis of refusing marijuana include living. This might seem awkward but its true. By refusing marijuana you might have a better chance of living. Say a person decided to take marijuana and one day decided to go to something worse so he took heroin. After a while this person got addicted and one day overdosed and died. See if he refused marijuana he probably wouldn’t have died that specific day. Marijuana itself doesn’t pose as a big threat. The things marijuana lead to is a much greater health risk. An example is as stated above. Marijuana is chemotherapeutic drug. This means that it can be used to treat certain types of cancer. The point of these past sentences is to make a point, the point is that marijuana can’t really affect the body of the abuser’s body since it is widely used in the practice of medicine. The things that marijuana can do to the body is as follows: make the eyes red, cause brain damage, low oxygen supply to the heart, and there is a possibility that it may even cause lung cancer. Marijuana might not have any major long-term affects but it sure has its immediate affects. These are more signs of use than immediate affects. For example one of them is loss of concentration. A person who is high (the state of mind a person reaches after the person uses marijuana) may not be able to concentrate on one thing. This can cause problems with a person’s schoolwork since schoolwork requires concentration. This might also affect a persons physical life since marijuana can immediately lead to loss of coordination in a humans body. These are other immediate affects or signs of use: loss of motivation and unusual fears of things. Bibliography: Rodney G.
